Immediately after their adventure with Professor Thorpe, and his bathosphere, Clark and Jimmy find a turtle with a message for help carved into its shell. It sets them out on a mission for Dead Man’s Island. Since the locals are afraid of the curse of the island, nobody will take them there for fear of crashing on the reef, or having their boat sink. Clark buys his own boat, but sure enough, when he and Jimmy get close, engine trouble arises, and their boat sinks. It will take a quick job from Superman to get them to the safety of the island.
