Enzo and Jacques have known each other for a long time. Their friendship started in their childhood days in the Mediterranean. They were not real friends in these days, but there was something they both loved and used to do the whole day long: diving. One day Jacques' father, who was a diver too, died in the Mediterranean sea. After that incident Enzo and Jacques lost contact. After several years, Enzo and Jacques had grown up, Johanna, a young clerk in an insurance office, has to go to Peru. There she meets Jacques who is being studied by a group of scientists. He dives for some minutes into ice-cold water and the scientists monitor his physical state that is more like a dolphin than human. Johanna can not believe what she sees and gets very interested in Jacques but she's unable to get acquainted with him. Some weeks later back in her office, she finds out that Jacques will be competing in a diving championship that takes place in Taormina, Sicily. In order to see Jacques again she makes up a story so the firm sends her to Italy for business purposes. In Taormina there is also Enzo, the reigning diving world champion. He knows that only Jacques can challenge and probably beat him. This time Johanna and Jacques get closer, but Jacques, being more a dolphin than man, cannot really commit and his rivalry with Enzo pushes both men into dangerous territory... 如果比全世界最孤单的海豚还寂寞。重归混沌。我们依然不是谁的谁。The end you did it alone.。那一抹令人沉醉的蓝色。再见，碧海蓝天。孤独的人鱼，忧郁的蓝。何必把人类的情感降低到如此卑微的地步？。即使远方除了遥远一无所有。在结局，我们独自做事情。无能为力的爱。 杰克（让-马克•巴尔 Jean-Marc Barr）在希腊海边长大，虽然小时候眼看着爸爸死于一次潜水事故，却没有削减杰克对大海的热爱。当杰克的朋友恩佐（让·雷诺 Jean Reno饰）找到他，劝说他参加潜水冠军大赛时，杰克答应了，在比赛中成绩突出勇夺冠军，并且得到了乔安娜（罗姗娜•阿奎特 Rosanna Arquette饰）的爱。两人打得火热，杰克却意识到他放不下、离不开大海。 意外发生了。好友恩佐在潜水中不幸丧生，杰克把恩佐的尸首放入大海当中，杰克的心中非常迷乱，他觉得自己不再属于人类社会，只想潜进深海，像海豚一样陪伴大海一生。尽管传来了乔安娜怀孕的消息，杰克深情的看了看爱人，转身投入了大海的怀抱。
