After officially dying and coming back to life, Stan decides to leave a legacy on the world and begins to search for legendary buried treasure. As the search for gold goes "North," life at home heads south as Hayley turns to body-piercing, Steve creates a robotic girlfriend and Roger files for sexual harassment.

When the CIA initiates an Alien Task Force, a peculiar twist of fate puts Roger in charge of the task force in disguise, who marks Stan as an alien to protect his own identity. Meanwhile Francine comes to grips with being left-handed.

Stan discovers that a former KGB agent he's been searching for is his new next-door neighbor and is trying to turn Steve into a communist. Meanwhile, Roger and Klaus head to Europe for a little R & R.

Francine pushes Stan to open up to her emotionally, but she gets more than she bargained for when he tells her that he killed her best friend's husband. Meanwhile, Roger becomes the family psychiatrist and Steve vows vengeance when Hayley kills the queen bee from his science project.

Feeling threatened by Stan's mother, to whom Stan is once again giving support with her failing relationships, Francine seeks to loosen the umbilical cord and find out what goes wrong with her boyfriends. Meanwhile, Steve accidentally catches the Ich from Klaus.
