Stranger By The Lake

40-year-old Franck spends his summer afternoons in a cruising area near a lake. His days are split between two men. With the first, Henri, a very strong and completely chaste friendship springs up. With the second one, Michel, it's true physical and passionate love. Michel is attractive, potent and lethally dangerous. Franck knows this, but wants to live out his passion anyway. Meanwhile, a man is murdered in the area and anyone could be the killer.
