Carnac beach in Brittany, during July. Alex, twenty years old, a seasonal worker at the Tennis Club, takes advantage of his freedom, goes out, meets people. Guillaume, 35 years old, comes on vacation with is wife and daughter. He spent his best summers at this beach when he was a younger man. Pierre, 50 years old, recently divorced, is on vacation with his two children and hopes to bond with them again. Sea, Sex & No Sun evokes the trials of three men from different generations, confronted with their desires and the difficulty of satisfying them. This comedy gently makes fun of men, those eternally dissatisfied creatures. At last a film about accepting oneself and letting go of one's fantasies. Summer is going to be hot... best keep in the shade!
