Lovewrecked tells the story of Jenny (Amanda Bynes), an eighteen year old girl who is ecstatic when she finds that her favourite rock star (Chris Carmack), is a guest at the tropical resort where she is working for the summer. When Jason falls off a cruise ship, Jenny dives in to save him, and the two raft their way into a neraby desert island - actually just a stones throw form the luxury resort.
However, Jenny wants to spend some time alone with Jason, so she lets him continue to believe that they are desparate castaways - at least for now. Things get even more complicated when Jennys rival Alexis pretends to be shipwrecked too, and they both compete for Jasons affections. When Jennys plan blows up in her face, her lifelong friend Ryan is there to pick up the pieces..
