Horrified by the pollution in the Pacific Richard Mariner and Nic Greenbaum finance an experiment - to throw a bottle into a Tokyo river and track it out into the ocean. Meanwhile Richard’s wife and Nic’s daughter will race across the ocean captaining rival yachts fighting to reach the bottle first - unaware that they will be tested to the limit. To generate extra publicity the bottle is filled with lottery tickets any one of which could be worth $110 million. But as it whirls towards the centre of a floating garbage patch the size of Texas a rumour begins to spread that it contains the winning ticket. So the experiment becomes a deadly game as lethally dangerous players become involved.
