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 decides he doesn't want to hang out with Stewie anymore, so Stewie tries to save their relationship by having a baby ... or seven ... by using Brian's DNA to impregnate himself. Meanwhile, Peter, Joe, Quagmire and Cleveland attempt to make a viral video.

When Quagmire opens a cat café in town, Brian decides to take a stand to get the café shut down. Meanwhile, when Meg and Chris get in trouble at school, Lois becomes nervous and decides they need to go to church camp in order to find their way.

Stewie's future life could not be going any better, living as a wealthy, old Mr. Burns-type man, until his retirement is interrupted by Brian, who brings news that Peter is dying.

When Peter starts coaching for Quahog's minor league baseball team, he gets constipated during the national anthem and must kneel, unintentionally becoming the face of racial justice.

Meg plans her wedding to an unexpected Quahog resident. Meanwhile, Peter finds a new vest and on one of many adventures fitting for his new attire, his arms are torn off and he is left with tiny hands that have yet to grow back.
