Mason Tucker, a passenger of American Skyways Flight 3108, en route from Florida to New Hampshire, believes he is headed home to his apartment and a cat named Bruno. But unbeknownst to him, the aging aircraft he is flying in will shortly be encountering severe weather, where it will be forced off course and sent directly over a mysterious section of ocean commonly known as the Bermuda Triangle.
There, buffeted on all sides by the treacherous elements, the plane encounters a strange vortex. Drawn in by it, Mason and his fellow hapless travelers can only hang on and struggle to survive as they are dragged out of their familiar world and propelled straight into the unimaginable.
