Recap: The state police send out an APB for a svelte blonde woman fleeing Ojai with a large German Shepherd...and the police have orders to shoot to kill Max. Nooooo!!
Miles north of Ojai, a cop stops in at his local market - just as the pickup truck carrying Jaime and Max pulls up. Jaime activates her bionic hearing and eavesdrops on the cop telling the shopkeeper he's on the lookout for her and Max...and the driver of the pickup sees her crouching behind the truck with Max and correctly assumes they're on the lam. He watches as the cop drives off, then tells Jaime he knows what it's like to avoid law enforcement...and she thanks him for his discretion, then bionically jogs off with Max.
After running through various meadows for awhile, Jaime and Max arrive at the ranger's office for the Hardin National Forest. She tells Max she hopes her old friend is inside...and that he'll be in a friendly state of mind when he sees her. When a homely young man with a dorky pageboy 'do answers the door, Jaime warmly says, "Hello Roger", and he contorts his face into a look of surprise, then invites her in and offers her coffee and sustenance. She sheepishly apologizes for the abrupt way she dumped him pre-Bionic Woman, and he breezily says it's understandable that she'd prefer to go on a tennis circuit, 'cause it had to have been more exciting than anything that was happening in this dull town. Jaime says she should have been more mature about their split and told him face-to-face he was getting the heave-ho, but he assures her he isn't upset with her...then turns his attention to Max and gushes about how much he loves dogs. He starts nattering about an Australian Shepherd he once had...and as he's going on and on about that, Jaime curls up on the couch behind him and nods off. Roger tucks her in with a blanket, then goes over to his desk and picks up a warning message he received earlier about Jaime and Max, which, funnily enough, includes his doodles of Jaime's name...like twelve year old girls like to do when they replace the dots over the "i" in their name with little hearts. He folds the paper and puts it into his pocket.
The state police receive word over their radios that they're to intensify their search for Jaime and Max.
Jaime wakes up after sleeping for seven hours...and by this time Roger has fed Max and is fixing the two of them some dinner. He places candles on the table and gets out a book of matches...and he and Jaime stare longingly into each others' eyes as they light the candles together. Max gets upset at the sight of the flames and starts barking, but Jaime and Roger just kind of shrug and assume he's jealous of their canoodling. Roger then brings over some steak in a pan he wants to flambé...but as soon as he lights up the meat, Max has a flashback of the lab fire, suffers a complete meltdown, and breaks down the front door in his desperation to flee. Jaime stares after him in puzzlement, while Roger is totally mystified as to how a dog could be strong enough to physically break through his front door. Jaime stares contemplatively into space as she replays the various freakouts she's witnessed Max have during this two-parter and finally twigs onto the common trigger: fire. When she blurts all this out to Roger, he tells her he knows about the APB and that the police have been given orders to shoot Max 'caused he's been classified as a dangerous animal. Jaime decides it's time to contact Oscar and Rudy...and fortunately is able to reach them at her apartment. She gives them her location, tells them that Max has only been acting out because of his deathly fear of fire, then implores Oscar to call off the shoot to kill order. Oscar replies, "Of course, babe" and calls off the APB. Phew!
Max is deep in the woods, gazing at a herd of sheep from several feet away. When a scary looking wolf suddenly appears, the sheep begin to bahh uneasily...and Max dashes over to protect the herd. When the wolf leaps in and grabs one of the sheep, Max confronts him, and the two growl and bite at each other until the wolf gets scared off and runs away. A nearby ranch owner named Harley hears the commotion, so he runs over with his rifle...and when he finds a mournful looking Max standing over the murdered sheep, he pulls the trigger and shoots Max in the jaw. Asshole.
Jaime tells Roger she just heard a gunshot, and a few seconds later Roger gets a call from Harley, who reports that he just shot at the dog who killed one of his sheep and warns him that the wounded beast is probably headed his way. Roger tells Jaime they need to find Max before Harley finishes him off...and then the camera pans over to the smoking bullet that just grazed Max, and it suddenly sparks a forest fire. Nice going, Harley. Asshole.
In the woods, Jaime and Roger encounter the wolf - ack! - and Roger puts his arm around Jaime and assures her that the animal is probably more frightened than she is. The wolf glares at the two of them with his blood soaked mouth before turning around and running off...and Roger wryly says, "Well, now we know who killed the sheep" and says he noticed that the wolf had bite wounds, most likely courtesy of Max.
Harley comes upon Max, who's writhing in pain from his jaw injury - but before he can aim his rifle and take another shot, he accidentally steps into a bear trap. Max trots over to where Harley is crying out for help and takes a moment to bionically bite his rifle in half - haha! - before using his superdog jaw strength to spring open the bear trap and release Harley's foot. Harley, who was terrified that Max was getting ready to feast on his trapped foot, looks befuddled and asks, "What kind of dog are you?" and Max races off, then has another flashback-fueled freakout when he notices that part of the forest is on fire.
Jaime and Roger find Max - but he's so upset by the forest fire that he leapfrogs over the two of them and scampers away. Jaime is about to chase after him, but Roger tells her it's a bad idea and that he needs to head back to his office and deal with extinguishing the fire.
Firemen arrive at the scene to combat the flames, while Roger sits in his office and doodles Jaime on his notepad before he decides he should probably get back into the forest to search for his beloved. Jaime, meanwhile, is racing through the fiery forest to catch up with Max, who's still in freak-out mode. Oscar and Rudy arrive at the outer perimeter of the fire...and when the Fire Boss tells them they can't hang around, they haughtily inform him they're from the OSI, and that it's a matter of national security that they locate Jaime and Max. The Fire Boss tells them that a ranger just dashed into the flaming forest to find them, and Oscar and Rudy exchange worried glances.
Max has more flashbacks of the lab fire as he narrowly escapes being flattened by a burning tree. Jaime finally locates him, but he's so deranged from the pain in his jaw that he attacks her and bites her bionic arm until she passes out. He immediately looks contrite and stares sadly in her direction.
Max licks Jaime's face in an attempt to revive her, and a few seconds later Roger finds the two of them and cuddles next to Jaime. She looks freaked out by having her arm bitten by Max, then shows Roger her damaged bionic limb with wires sticking out of it. When he's all, "WTF?!", she spills the beans on the OSI secret [that Rudy and Oscar have been afraid since Part 1 would get out to the general public...so, well done, Jaime] that both she and Max are bionic...and that when Harley shot Max in the jaw, it short-circuited his wires and caused his brain to go all squirrelly. A bemused Roger's like, "Er, OK..?" then tells her that there's a steam engine nearby, and if they can get it to work, there's a chance the three of them can escape the flames via rail.
Jaime and Roger quickly locate the steam engine, bring Max aboard, and Jaime doesn't bother hiding her bionic strength from Roger when she forcibly pushes the gear into place.
The Fire Boss tells Rudy and Oscar about the parked steam engine and correctly assumes that Jaime and Roger will try to escape the fire on that.
The train starts chugging along the tracks...and when the wheels stick, Jaime hops out and gives the engine a bionic shove to get it moving again. Roger for some reason looks stunned and asks, "Can I ask how you did that?" and she says no, even though she had just revealed her bionics (and Max's bionics) to him a few minutes earlier. As the train glides through the fiery forest, Jaime and Roger breathe into wet handkerchiefs while Max whines anxiously. The Fire Boss and his team station themselves at the end of the tracks where they hope Jaime and Roger will soon materialize.
Roger suffers from smoke inhalation and keels over...and then the train comes to an abrupt stop after a tree falls on the tracks. Jaime also weakens from breathing in too much smoke, bionically hears the firemen talking nearby, and tells a panicked Max to go over to them for help. He's like, "I'm on it!", has flashbacks of all the fun times he and Jaime had together in Part 1, and scampers off toward the firemen.
Max arrives at where the firemen, along with Oscar and Rudy are stationed. They're like, "Max! Where's Jaime?!" and he barks, "She's over here!" and leads them to the steam engine. They quickly find Jaime and Roger, carry them out of the train and administer oxygen, and are relieved when they each start to breathe. Rudy gives Max, who fortunately doesn't try to maul him to death, a grateful hug and coos, "Good boy!" and Oscar stares down at Jaime-babe with tears of joy in his eyes.
Once the fire is under control, Harley tells the firemen about the gun eating dog he encountered in the woods, but they don't buy his story...or seem to be aware that the smoking bullet from his dickish shooting of Max just caused a major forest fire. Rudy tells Jaime he's reconsidered putting Max down and instead is going to help him overcome his fear of fire...and that he's going to do it while also allowing him to frolic outdoors. After that, they might let Jaime or Roger adopt him...and Jaime tells Roger if he gets custody of the pooch she definitely wants visiting privileges. Roger grins and says, "That's the idea", but Oscar solemnly informs them that the final decision of re-homing will be up to Max.
As it should be. Woof!
