It’s time for the family vacation, and the Camdens are having their most depressing one yet. At their beach house, each member has something to worry about. Simon accidentally “killed” a classmate in a car crash. Kevin and Lucy are concerned about having children. Ruthie is bothered by how Peter keeps tagging along with the family, and later even learns a secret of Mary’s. Eric and Annie are still working out their marriage, but it’s proving too difficult to handle.
