Jenny (Bynes), an eighteen year-old girl who is ecstatic when she finds that her favorite rock star, Jason (Carmack), is a guest at the tropical resort where she is working for the summer. When they are both thrown overboard during a cruise, Jenny is even more thrilled to find herself stranded on a remote beach, alone with Jason. Jenny soon learns that they are actually just down the beach from the resort - but Jenny keeps the truth from Jason so that she will have a chance to win him over. Things get even more complicated when Jenny's rival Alexis pretends to be shipwrecked too, and they must compete for Jason's affections.
