Enzo and jacques really are some of friends who share a passion because of the dangerous sport of free diving, and that have already been close since youth. Expert diver Jacques chosen to follow the footsteps of the father, who died at sea when Jacques was a boy. Into the bewilderment of scientists,'' Jacques harbors an amazing power to adjust his pulse and breathing pattern in the water, to ensure 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 vie against him in a free diving competition -- determining who can dive deeper and longer without scuba gear -- Jacques meets Johana, a beautiful insurance investigator from America, and he discovers that he has to choose between his love for her and his love of the ocean.
