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.

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.
