Sandy and Michael's father has just gotten a divorce and the family decides to go out to California to visit him. Grandpa Lloyd has taken to living on a boat and has plans to sail to Tahiti, something which Sandy is adamantly against. Meanwhile, David becomes a crew member of a film being shot on the beach.

Sandy and Michael fear the worst when Lloyd disappears but breath a sigh of relief when he is found safe. Later, Sandy tries to talk him into moving in with the family, instead of living on a boat. David's movie crew gig goes awry and Cara makes an unexpected visit, surprising a preoccupied Mark.
