In 1982 in the German town of Leimen, tennis coach Günther Bosch discovers a boisterous boy with an irrepressible will to win: Boris Becker. He takes him under his wing, moves to Monte Carlo with him and coaches him to become the youngest Wimbledon winner of all time in 1985 at the age of 17. The trio seems to have reached their goal, but the real work only begins now.
