By chance, Bertrand, a middle-aged man who suffered from unemployment and depression, joined the men's synchronized swimming team.

Although the coach was once a world champion, he is now an alcoholic... Can this "loser alliance" successfully counterattack and become the savior of the French men's synchronized swimming world?
