After attending a nuclear power convention with Lenny and Carl; and not returning until a week after the convention ended, Homer's attitude changes drastically, as he no longer is eating fat foods or drinking beer, and manages to satisfy Marge in bed better since the conference. Lisa begins to investigate her dad. She finds blueprints of the nuclear plant and sees him praying to Mecca on a prayer mat, making her believe Homer may be planning a terrorist attack on the nuclear plant. Lisa calls FBI agent Annie Crawford to do a further investigation, where she grows a slight attraction to Homer in the process. One day, Homer goes to the nuclear plant with an unfamiliar device. Lisa follows Homer there, and he reveals that at the convention, he befriended a group of hippies, who hypnotized him with music from Grateful Dead and encouraged him to lead a more environmentally-considerate life. It is also revealed that Homer's prayer mat was actually a relaxation mat given to him from the hippies. The device in question that Homer has would destroy the plant's air conditioning device should it be activated. But before he can turn it on, Crawford arrests him. Lisa, now proud of her father's project, turns on the device before Chief Wiggum can stop her. Despite the device turning on, nothing happens, as Mr. Burns reveals that the plant does not have air conditioning. Mr. Burns is then arrested for his lack of installing a proper system in the plant. Homer then begins drinking beer again, after grabbing a beer from a parachute (that was launched by Moe), and reverting to his old ways.
