While going through a tunnel, the train crashes into the road block and the guards shot dead. Randolph's men then secure the train and Randolph orders Jason Locke and Gregori Nobokov to open the door, but they refuse. Randolph tells Locke that he and his team developed the gas and he refuses to let it go to waste. Randolph has his men remove the gas canisters and put them on trucks. Randolph asks Locke for the code to open the canisters and when Locke tells him no, threatens to use truth serum on him. Locke and Nobokov manage to steal rifles from their guards, but Nobokov is wounded when he is hit with grenade shrapnel. Randolph injects the truth serum into the dying Nobokov. Nobokov tells Randolph this was his last assignment and his goal was to kill Locke. Nobokov gives Randolph his half of the combination and Jenson tells Randolph, Airwolf is flying around the area. St. John sneaks into the mountain and shoots Randolph dead.
