The Terminator: Death Valley
When a member of Killerman's gang, Donnie, was captured by the mercenary Bounty Hunter VanDirk and forced across the desert barefoot to reveal the location of the hideout, Killerman and his gang gunned him down. As this happens, the Terminators D810.X and D800.L arrive via TDE jump only a mile away, and detect the hideout as a source of clothes, weapons, and information. While The Bounty Hunter confronted the gang, the Terminators entered the hideout and begin systematically terminating gang members, asking for information about the Connors. Unfortunately for him, in a ploy to distract the Terminators for an ambush attack, Killerman says he knows the Connors but won't tell them as he initiates a counterattack. As the battle ensues. Cindy is accidentally shot by VanDirk and the rest of the members of Killerman's gang are terminated as Killerman collapses the cavern entrance with dynamite as he makes a break for it. The Bounty Hunter is left wounded in the wreckage of the gang's cavern lair, while Killerman escapes on his bike. The Terminators, certain Killerman has useful information, break free and set out in pursuit on the remaining gang motorcycles after securing clothes and weapons. The Bounty Hunter survived the devastation.
Killerman flees to the Furnace Creek Visitor's Center and tries to lose himself in the crowds. The Terminators follow and decide on direct action to capture their target, charging in and laying waste to the occupants. VanDirk finally regains consciousness and crawls out of the cavern and back to his vehicle. The Terminators change their disguise to that of park rangers and continue their pursuit of Killerman. Choosing to go off-road to evade police inquiry into his disastrous and unlicensed pursuit of the gang, VanDirk runs his vehicle into the mud beds and wrecks. He is rescued by an old gold prospector, Scotty and his mule Jezebel. Killerman decides that his only chance for survival is to give the Terminators what they want, and he sets out to find the Connors.
The Norden family, Ken, Sara, and their son Jon have been living in a camper in the ruins of an old ghost town while Ken works on environmental studies for two weeks. Sara has reached the breaking point and declares she is going to take Jon and return to San Francisco. D810.X begins to ask D800.L probing questions about humanity while scanning a remote desert grave (David Foster-1911-Heatstroke). Killerman takes the Nordens hostage, because they are the only John and Sarah he knows of.
The Terminators' vehicle also falls prey to the hazards of the desert floor and they are delayed in their pursuit of Killerman again. With the Terminators closing on him at the Nordens camp, Killerman realizes that his pursuers aren't going to be interested in deals and flees into the desert with his captives after crashing an old mine cart onto them.
With darkness falling and a storm on the way, Killerman forces the Nordens to make camp at an old rail line station, where the Terminators catch up with them after dawn. Killerman forces Ken out to negotiate with the machines and got him terminated for his troubles. This drove Sara to attack Killerman in a rage. The tables were turned however when VanDirk and Scotty crash a locomotive into the Terminators as they closed on the battling humans.
After pleading for his life, Killerman was allowed to join the rest of the humans fleeing the machines in the train. D810.X continued the pursuit of the humans while D800.L repaired itself and boarded the train on a mission of death. Killerman redeemed himself (at least a little) in the eyes of VanDirk by sacrificing himself in hand-to-hand combat against D810.X as the train rocketed out of control around a curve, allowing the survivors a chance to escape before it derailed.
