Sink or Swim

Le grand bain is a movie starring Mathieu Amalric, Guillaume Canet, and Benoît Poelvoorde. A depressed man joins a synchronized swimming team made up of middle aged men.
40-year-old Bertrand has been suffering from depression for the last two years and is barely able to keep his head above water. Despite the medication he gulps down all day, every day, and his wife's encouragement, he is unable to find any meaning in his life. Curiously, he will end up finding this sense of purpose at the swimming pool, by joining an all-male synchronised swimming team.
