Peter accidentally loses the reservation for Stewie's first birthday party at a local restaurant, and must create a new party. Meanwhile, Stewie misinterprets the meaning of "birthday" and assumes that the same mysterious "Man in White" who delivered him as an infant will be returning to force him back into Lois' womb. Peter fails to put together a party in time for Stewie's birthday, and reroutes a circus parade into the Griffins' backyard. Peter gives Meg permission to go to a "party" at her friend's house, not realizing that it is a cult meeting where the members will commit mass suicide by drinking poisoned punch. Peter retrieves Meg before the cult members drink the punch. The cult leader notices that Meg did not drink; he puts on his white robe and goes to the Griffins' house. Stewie traps and kills the cult leader, thinking he is the "Man in White".
