Recap: Jaime is flying over the Atlantic Ocean on a large military plane with her former doctor and creepish admirer dork, Michael Marchetti. They're on their way to London to pick up some top secret biomedical gear, but first need to make a refueling stop on Alaska's Grand Tooley Island. Jaime pops into the cockpit to chat with the three military pilots, who are preparing to make their descent. One of the pilots, Major Andrews, tells Jaime that the island is a deactivated military base that houses a biological research facility, and the scientists who reside there are experimenting with the tundra to see if anything can grow on it. The air traffic controller on the island clears them to land...but as he's giving them landing instructions, he seems to space out, then stops talking altogether. Major Andrews scrunches his face confusedly and tries to re-connect with him or anyone else on the ground...and when he doesn't get a reply, he says it appears that something very weird is happening on the island - but that they have no choice but to land 'cause they're low on fuel. A problem he could have solved by not flying them so far north that they ended up anywhere near Alaska, which seems like a really strange detour to make while en route to London.
When they land on the runway, they're met with eerie silence: no ground crew, or other signs of life whatsoever. Jaime activates her bionic hearing...and when it registers nothing, she stares at Michael worriedly and wails, "Where are all the peeeeeeeeeeople?!"
The group wanders around the base yelling "Hellooooo..?!", shut off a car they find idling, then amble into an abandoned mess hall. The camera pans in for a needless close-up of the food that was about to be served: a row of wieners and iceberg lettuce. 'Cause nothing satisfies the masses like a hearty wiener salad. As panic starts to set in, Michael suggests they split up and look around - even though no good ever comes from a group splitting up in these types of TV situations - then reconvene at the mess hall for a weenie roast.
Jaime partners with Sergeant Roberts to explore the base...and when they arrive at a hangar with a door that seems bolted shut, Jaime bionically forces it open. A scared young blonde woman is hiding in the cockpit of one of the planes inside the hangar - but neither Jaime nor Sergeant Roberts sees her. As Jaime hovers close to the exit, the sergeant wanders deeper inside the building and disappears from view...and when Jaime calls for him a few seconds later, she gets no response. She becomes so frightened that she flees the hangar and runs straight into Major Andrews, who I thought got a little too touchy-feely while comforting her. She tells him that Sergeant Roberts just disappeared somewhere inside the hangar, so Major Andrews says he'll go in and look for him 'cause what could go wrong with that...and a few seconds later, he too disappears while letting out a big burp (yes, that sound effect really happened). Jaime runs outside again and begins to have a full on meltdown just as Michael rushes over. She tells him about the disappearance of the major and sergeant, and Michael wisely decides to not enter the hangar to look around. The two vow to stay together, then head over to the Agricultural Research Station.
Jaime and Michael enter a control room with lots of impressive looking dashboards that have thick, color-lit buttons. They notice an isolation chamber housing a giant rock, which Michael identifies as a meteorite. They spot a radio receiver and rush over to see if they can contact Oscar...but it soon becomes clear that while they can hear Oscar, he's unable to hear them. A panicked Jaime wails at Michael, "What do you think is going onnnnnn??" and he stares back at her with a grim expression and says that some mysterious force is preventing anyone on the island from communicating with the outside world. Like maybe sunspots...or other stuff. LOL. Thanks, professor.
Inside the hangar, the young blonde woman who was hiding peeks up from the cockpit of the plane. We then hear footsteps...and when the camera pans down, we see that the feet belong to Major Andrews, who has a blank expression on his face and is wandering around like a robotic zombie.
Back in the control room, Jaime and Michael find a file labelled Dr. Boylin, who Michael says is the head of research. Jaime finds a videotape tape dated for that day, so they put it into the player in case it yields any helpful clues. The tape (narrated by Dr. Boylin) includes video footage of a truck arriving in the hangar, and then various military personnel unloading the meteorite, which apparently landed on earth seven million years ago. The tape then cuts over to the isolation chamber, where a group of scientists are poking at the meteorite and noting the charred residue on its pitted surface. Dr. Boylin is heard to exclaim, "Incredible! It's alive! This structure violates all generic laws of life as we know them!" LOL. As the scientists continue to poke at the thing, measure its pulse, and document its size changes, they notice that it seems to react to heat. A few seconds later, they figure out it probably wasn't the best idea to apply heat to the peculiar specimen, 'cause they all become faint and keel over inside the chamber...and the videorecording abruptly stops. Michael stares at the blank TV screen in puzzlement, then at the meteorite, and remarks on how harmless it looks.
The zombified Major Andrews enters the research station and turns up the heat in the control room. Jaime detects his footsteps with her bionic hearing, then tells Michael she can feel the room getting warmer. The meteorite responds to the heat and starts pulsating - a reaction that causes Jaime and Michael to suddenly develop debilitating headaches. Jaime manager to flee the control room and bionically race out of the building...but leaves behind a weakened Michael, who is powerless to move and passes out. As Jaime flails around the base in full on panic mode, she encounters the zombified Major Andrews and Sergeant Roberts, who robotically march towards her with blank expressions. She freaks out even more when she spots an entire herd of Walking Dead like zombies on the runway tarmac, also robotically marching in her direction. She flees to the hangar and bionically slams the door shut, then spots the young blonde woman, who identifies herself as Laurie Boylin (the head researcher's daughter). Jaime assures the tearful girl that everything will magically sort itself out before the end credits roll - but in the meantime, they're in this together. The zombie herd arrives at the hangar and starts banging on the door, so Jaime races across the building and bionically kicks a flimsy looking wall to create an escape route. She suggests to Laurie that they hide at her house, and the two race to the nearest car...but as the herd closes in, Jaime is suddenly incapacitated by a headache and collapses. She yells at Laurie to help her, but Laurie doesn't respond and continues running towards the car - and somehow Jaime manages to scramble to her feet and reaches the car before getting...well, I dunno if devoured is the right word since they don't really seem like flesh eating type zombies, so I'll just go with overpowered.
Night has fallen by the time Jaime and Laurie arrive at the Boylin house. Jaime asks her new young friend why she's seemingly immune to zombification, and Laurie says she's deaf but can read lips...and Jaime's like, "Ooooh.." since it also explains why she didn't respond to her cry for help in the previous scene. She then deduces that since Laurie is deaf and she has a bionic ear, the meteorite must be zombifying people by way of the ear canal. Seems reasonable.
The zombie herd has somehow gathered flashlights for the march over to the Boylin house, and they're now banging on the door. As they easily break in, Jaime bionically breaks a window so that she and Laurie can climb through it and escape. They take a quick rest on the curb, and Jaime theorizes about how the meteorite must be giving off sound impulses to anyone with normally functioning hearing. She suddenly hears Michael calling her name...but since he too has been zombified, he spacily offers to disconnect her bionic ear so that she too can join the herd. Jaime tries to get through to him by imploring him to tell her what kind of life form the meteorite is, and he woodenly replies, "We have to protect it." When Jaime asks what will destroy it, he regains coherence for a few seconds and yells, "Run Jaime! It's too strong!" and Jaime and Laurie are all, "Ack!" and promptly flee - just as Michael's brain zombifies again and he yells at her to come back.
Jaime and Laurie return to the base, and Jaime thinks hard about how to deal with the bizarre crisis at hand. She decides that since heat seems to power the meteorite, perhaps cold could be used to fight it. Seems reasonable.
The zombies carefully place the meteorite in a large wooden box, and Jaime and Laurie hide behind a row of steel drums and watch them load it onto the military plane. Jaime asks Laurie what the coldest thing on the base is, and Laurie says the liquid CO2 that's stored in the fire department is pretty damn cold...so Jaime tells Laurie to stay put, then bionically races across the base wearing a pair of protective earphones to prevent another debilitating headache. She quickly finds a CO2 tank in one of the fire trucks, then gets into the driver's seat and drives it onto the plane the zombies are readying for takeoff. She bionically leaps over the firetruck, battles severe head pain after Zombie Michael steals her earphones, and swats away several of the other zombies. She begins spraying the meteorite with CO2...and this seems to do the trick, 'cause eventually everyone's mental fog lifts, and they all become de-zombified and start acting like their normal selves again. They shake their heads in bemusement and are all, "Wha-at's going on?" and Jaime collapses against Michael in relief.
Oscar is en route to Grand Tooley Island and is assured by the people on the ground that everything is back to normal. The meteorite is still being stored there - but to be safe, they're keeping the nasty fucker on ice.
Dr. Boylin debriefs Oscar about the meteorite being a very curious life form that was able to communicate ultrasonically...and when it corresponds with alpha waves in the human mind, its signal blocks out any thoughts except its basic instinct to survive. Jaime gasps and calls it fascinating...and Oscar gives her a funny look and is all, "You're fascinated after everything you've just been through?" Jaime says she is, then expresses deep wonderment about this new life form and where it could have come from.
Either a quarry, or the show's props department.
