Disa and Tommy are board by catching small fishes by the pier. They get a hold of a boat and head out to sea to catch a big one. But the fight with the big one turns out to be more than they can handle and soon they find themselves stranded on a reef. They on one reef and their boat on an other. The tie starts coming in and the fight with the big one is not over.
