In this week's show four couples arrive on Prize Island to compete in thrilling games like ‘Leaving On A Jetty Plane', ‘Shipwreck' and ‘Mine Swing'. After each round a team is eliminated, leaving only one couple to compete in the final located at the remote and mysterious Moonfish Bay. In ‘Buried Treasure' the finalists will attempt to locate and win the ultimate prize buried in the sands - a new car and £50,000.
