The career of TV star Josh Anders is all washed up. The ratings on his nature TV show, “Diver Down,” are residing on the ocean floor, but he has been thrown a life preserver by a billionaire who wants to use his fading celebrity to convince the residents of a Caribbean island to sell their land. So Josh travels to Cayman Brac to help the real-estate tycoon buy the land he needs to build a resort, but some of the landowners aren’t sold on the idea. Meanwhile, Josh meets a pretty dive-shop owner and a young boy who will change his life far more than a billionaire ever could.
