Homer becomes obsessed with a 1980s family sitcom and starts acting like the show's father. Emulating this character's values, he refuses to give Bart a mini-bike he wants, because Bart would never learn to appreciate things if they come to him too easily.

Bart then realizes that he could sell secrets about the nuclear power plant to other countries. He agrees to sell them to China in exchange for a mini-bike. To gain access to the nuclear plant's computer system, Bart begins doing typical father-son activities with Homer, eventually leading to Homer bringing Bart to work. When Homer falls asleep, Bart goes around the plant downloading information onto a USB storage device.

After Bart leaves the flashdrive with the downloaded data at the zoo and takes the bike, Homer reveals to him that he did buy him the mini-bike too, for being such a good child. Bart, feeling bad for betraying his country rushes back to the zoo in attempt to recover the flashdrive. There he meets the Chinese agents, who threaten to kill him if he does not cooperate. Homer steps in and offers himself in Bart's place, as he has a lifetime of nuclear experience. In China, he leads the construction of a nuclear power plant, which explodes right after the grand opening ceremony. Back at the house, Bart tells Homer how much he appreciates him, and that they have "the best kind of bonding": sitting in front of the television while making no eye contact at all.
