Two men answer the call of the ocean in this romantic fantasy-adventure. Jacques and Enzo are a pair of friends who have been close since childhood, and who share a passion for the dangerous sport of free diving. Professional diver Jacques opted to follow in the footsteps of his father, who died at sea when Jacques was a boy; to the bewilderment of scientists, Jacques harbors a remarkable ability to adjust his heart rate and breathing pattern in the water, so that his vital signs more closely resemble that of dolphins than men (he even considers a school of dolphins as his extended family). As Enzo persuades a reluctant Jacques to compete against him in a free diving contest — determining who can dive deeper and longer without scuba gear — Jacques meets Johana, a beautiful insurance investigator from America, and he finds that he must choose between his love for her and his love of the sea.

A beautiful felon, sentenced to life in prison for the murder of a policeman, is given a second chance – as a secret political assassin controlled by the government.

The charismatic criminal Dobermann, who got his first gun when he was christened, leads a gang of brutal robbers. After a complex and brutal bank robbery, they are being hunted by the Paris police. The hunt is led by the sadistic cop Christini, who only has one goal: to catch Dobermann at any cost.
