Sidney and Natalie Monty are travelling home after a fabulous holiday in Canada and America when their Boeing 747 is hijacked and all the passengers on board are gassed except by a quirk of fate, Natalie. The plane is belly flopped down where it eventually breaks up and sinks. She swims to a small island not far away but before she escapes to Nassau, witnesses some brutal murders by Le Frisk who is after the gold bullion on board the sunken plane. Befriended by Noel Sommerville, head of security at the British Consulate, are both drawn into a cat and mouse game of catching Le Frisk following the trail of fear and murder he leaves behind in his wake.
