Yet, when Sam refuses to move the carp he's keeping in their extra bathroom, Molly becomes fed up and unexpectedly leaves. Molly moves in with their grown son, Joel, and starts dating an old friend. The couple's daughter, Ruth, convinces Sam to try to win his wife back and rediscover his own sense of romance.
