Childhood friends Jacques and Enzo share a passion for the danger of free diving. Jacques, following in the footsteps of his father, who died at sea when Jacques was a boy, harbors a remarkable ability to adjust his heart rate and breathing patterns in the water, with his vital signs more closely resembling those of dolphins than men.

Besson and star Jean-Marc Barr were real-life diving buddies; much of Jacques's physiology was based on Mayol's actual records.
