As the Griffin family is preparing for Christmas, Peter tells his own version of the Nativity story.

An accident leaves Peter with a high-pitched voice, so Jesus coaches him into fending off the choir boys; Stewie is attracted to Lois' new masculine physique.

Brian becomes romantically interested in someone and it inspires him to use Stewie's time machine. Strange consequences result from their journey.

When Stewie sees a tag on Rupert reading "Made in China," he heads off to China to meet Rupert's family.

Lois embarks on a journey of self-discovery.
