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.
The show revolves around C.I.A. Agent Stan Smith, and his not so average family. Stan is constantly fighting off terrorists who threaten the safety of the United States, sometimes causing more harm than good.
His wife Francine is your average house wife. She juggles Stan and the kids while keeping a sound mind. Hayley, Stan's only daughter, is your average rebellious teenager. She speaks her own mind, and does things her own way.
Steve, Stan's only son, is a bit of a "geek". He enjoys games like Dungeons and Dragons, and participating in comic book conventions. Although he's not Stan's dream son, he always makes him proud.
Then there's Roger, the illegal alien (literally) who the Smith's are keeping protected. Roger deals with your average alien emotions, and the fact that he is not allowed out in public, which causes him great distress.
Last but not least, Klaus, the Smith's wisecracking talking fish (well, after he was removed from his body) who is secretly in love with Francine.
