Chris and Meg think their parents have it easy, and Peter and Lois beg to differ, so in order to teach them a lesson, they all trade roles. Chris goes to work at the brewery while Meg runs the house. While things start off well, it's not long until the stress of running a household and being the sole breadwinner break down Chris and Meg.

When Mayor West marries Lois' sister, Carol, 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.
