Stan Smith uses his CIA skills to help 13-year-old son Steve win class president and the heart of the hottest girl in class, Lisa Silver. But when being class president makes Steve mad with power, Stan must jump in to save the day. Meanwhile, Roger, the alien Stan saved from Area 51, helps 18-year-old Hayley with her school paper. In return, she hooks him up with boatloads of junk food to curb his sweet tooth. Unfortunately, some Chocodiles send him over the edge and a sugar crash prohibits him from finishing one of her papers, forcing Hayley to pick up the pieces. And Klaus, the goldfish with the brain of a German guy, pines after mother Francine. Unfortunately for Klaus, the closest he'll ever get to a date with her is the spin cycle with her sports bra.

Hayley comes home from a Green Party rally with her hair dyed green, instigating a fight with Stan. While she's sleeping, Stan cuts her hair (for her own good, of course). After learning of what Stan did, a wigged Hayley defies her father yet again by moving into the van of her new boyfriend. When Stan cuts her off financially, she gets a job as a waitress in a strip club, which pushes Stan right off the edge. Meanwhile, Steve tries to pass Roger off as his disfigured sister in order to cop a feel with a female classmate.

When Stan forgets his anniversary, he arranges to have 20 hours of Francine's memory erased, but the CIA temp on duty accidentally erases 20 years. Francine, having reverted to her wild child days, moves into her old apartment with Hayley as a roommate, and ends up going to a festival with Hayley's boyfriend. Meanwhile, Steve asks a good-looking girl out, but needs his wingman, Roger, to "jump on a grenade" for him and date her ugly cousin.

Stan invites his boss over for dinner, but the Smith family fears getting caught hiding Roger. After a close-call, Roger goes into a coma, making everyone thinking he's dead. After the family disposes of his body, Roger tries to get back home, but he ends up in another risky situation with the CIA.

Francine decides to throw a block party to get in touch with the neighborhood. Stan learns his new neighbors are Iranian and immediately suspects that they are terrorists. To prepare Steve for living near terrorists, Stan makes Steve join a group of scouts, who turn out to be trouble makers. Roger is convinced he possesses hidden alien powers and is determined to find out what they are.

Stan goes to great lengths to compete against his rival, Chuck White, and become the new deacon of their church. Meanwhile, Roger's "temporary problem," which Stan tries to use to his advantage, causes all sorts of problems for Steve, Betsy, the rest of the family, and eventually, Stan.
