"Men Who Swim," about documentarian Dylan Williams' all-male synchronized swimming team in Sweden. The men take part in the sport's unofficial championship in Milan in 2009, a pivotal year for many of them for another reason: They're turning 40. The members, including train drivers, meat buyers and teachers, have to overcome their initial hesitations in order to hone their routines, which are inspired by legendary swimmer Esther Williams. They also take stock of their middle-aged lives.
