Lily York has slipped away from the ever-present bustle of Hollywood for the quiet comforts of Orpheus Island. She was looking for some rest and relaxation off the coast of Austrailia, but fate had made other arrangements. First she has to deal with a drunken ex-boyfriend living at the resort. Ivan Abnet was less than thrilled to see her arrive, but after enough drinks, she's not his concern. Despite their history, she plans to ignore him and enjoy her vacation. Her only real complaint is the nightly swarming of thousands of small crabs scuttling across the beaches. But they're easlily avoided. But then some of the other guests begin to go missing. As more guests and staff disappear, panic begins. The crab swarms are everywhere...and more and more of them are giants, some of them several feet in size. Lily and Ivan are quickly trapped in the storm-racked resort by the Horror From The Sea!
