They end up investigating evidence of a giant turtle inhabiting the local waters.Magnus also meets a mysterious, beautiful woman named Jennie Haniver, who turns out to have been a childhood playmate of his; in fact, he’s still wearing the seashell necklace she gave him. The thing is, she only appears when he’s alone, and even Eric tells Magnus that they believed Jennie was just an Imaginary Friend of his. He insists that she was real, and that he even carved his and Jennie’s initials on the back of a turtle they played with.Eric’s wife explains that Jennie Haniver is a local Urban Legend: Two hundred years ago, a young woman whose ship sank in a storm in the Bermuda Triangle made a Deal with the Devil so that she would survive. Naturally Magnus refuses to believe it is the same Jennie.Eric becomes obsessed with catching the giant turtle and against all warnings uses a harpoon cannon on it. This just leads to the creature killing him and Dr. Paulus. Jennie is revealed as indeed being supernatural in the process. Magnus survives the incident however.The movie ends with Magnus leaving Bermuda, and throwing the seashell necklace into the sea. Then we see the giant turtle swimming below and are shown that it still has the lovers’ initials carved on its shell.
