The episode opens up on a train. Gadget, Penny, and Brain are on the train waiting for Quimby's orders. Quimby soon arrives with the assignment and Gadget is ordered to protect computer parts from Claw. Gadget talks to a bird behind bars and it leads him on a wild goose chase. Gadget says to never trust a bird behind bars.
The conductor, who works for Claw, tries to get rid of Gadget ― unsuccessfully, as usual. Gadget interrogates the engineer, unaware that he's not a M.A.D. agent. Penny finds out that Claw plans to hijack the train and warns the engineer, but they're knocked out by the sleeping gas.
Soon, the train arrives at Claw's headquarters. Brain wakes Penny up and the conductor tells Gadget that they made it. He sends Gadget to Claw with some boxes. Claw turns as Gadget comes in and he thanks the inspector for his work.
Gadget steps into the elevator, and Claw plunges Gadget to his death, but Penny fights Claw and saves her uncle, who turns out to be all right. Penny then re-hijacks the train and gets out.
Later, Chief Quimby congratulates Inspector Gadget for saving computer parts. Penny tells Quimby that Gadget tricked Claw by giving him the wrong boxes; it is revealed that the boxes have cat food in them.
On the train, Gadget gives Penny, Brain, everybody at home some safety tips for being on a train: He says not to bother people when they're walking and if the viewers have to bring their dog, make sure he stays still.
