To help Chris ace his ninth grade history class, Stewie and Brian employ the time travel machine for educational purposes. Not surprisingly, all three get stuck in the past.

Brian gets a gig writing for a teen magazine about the average American girl, but when he starts trailing Meg for research he discovers that her desperate attempts at dating have led her to a guy in the slammer. When Brian tries to expose Meg’s secret to the family, he finds that her boyfriend, Luke (guest voice Chace Crawford), has broken out of jail and has been hiding in the Griffin’s house.

When Mayor West marries Lois’ sister, Carol (guest voice Julie Hagerty), they move into the Griffin’s house to be one big “happy” family. To make room for everyone, Stewie is bumped out of his room and takes over Chris’ room, but not everyone is annoyed by the change. Peter and Mayor West bond and become best friends.

While all of Quahog assumes she's dead, Lois returns from the wilderness and names Stewie as her killer, but he goes on the run while Joe leads a manhunt around Quahog. Then, Stewie tries to take over the world and in the interim auditions for the American Idol judges Simon Cowell, Randy Jackson and Paula Abdul. Meanwhile, Lois realizes that she must stop Stewie.

After Peter buys a military tank with Meg's money, her car fund goes out the window and she's forced to get a job at the newly built Superstore in town. However, the town's economy begins to suffer when Superstore puts all the mom-and-pop shops out of business and sucks up the city's power supply. Brian and Stewie decide to take matters into their own hands in order to save the town from the corporate giant.
