A fantastic adventure that the protagonists will never forget.
An airplane suffers an accident in an unspecified location on the coast of Indonesia. The only four survivors take shelter on a small deserted island, waiting for the rescue teams to arrive. While waiting, strange events begin to occur, leading the castaways to suspect that they are not alone and that there is someone else there besides them.
Everything gets complicated when they decide to take refuge in a damaged ship that has run aground on the reef, and a massive walrus prevents anyone from approaching.
