汉普湾的不雅光旺季行将到临，帆船年夜赛也将睁开，不外却产生了沙鱼事务方巨贾及主办人山姆路易斯执意不延后角逐及封闭海滩，觉得能用沙鱼网禁止任何沙鱼进进，不意这条食人巨鲨是颠末水兵训的杀人机械，不单闯进赛，肆恣猎杀选手们，以后更杀死所有追捕它的人。海洋学家比利和索伦家人要若何对于这恐怖的怪物呢？

不与任何人比较，我为我的球队拥有这样的精神感到满意。

Sometime in the near future, paraplegic prison inmate Matt Mills meets The Board of Satoshi-Telefair Industries, who thank him for joining the Program. Under pressure and with a promise to make him walk again, Mills agrees to volunteer. He is injected with a synthetic nanomaterial and suffocated, only to wake up with restored use of his legs, yet alone in a steel cell in the first spoke of an experimental apparatus - The Wheel. A series of assailants inflict a multitude of damage to Mills body and torment his mind, yet the synthetic nanomaterial not only restores his damaged organs, it re-engineers his strength. The experiment might be designed to kill, but Mills is determined to survive - and get back to his daughter before The Board finds her first.
