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.

Steve and his friends take up witchcraft to gain power and popularity at school. Stan and Klaus become obsessed with remembering 90s bands.

Klaus gets transferred into the navigation system of Stan's car when Stan refuses to pay for life-saving surgery; Steve and his friends prank Roger, who then terrorizes them for revenge.
