At the crossroads of a city, at the crossroads of sports, the Vaudoise arena vibrates with passion. Dive into the heart of the action, from spectator to actor, from amateur to elite athlete, from preparation to action, on the ice, in the air at the top of the diving board, underwater following the line, foil or racket in hand. Reproducing the energy conveyed by the sport and the shows, the film links rhythmic and vibrant shots in a succession of emotions that lead to the climax: the victory, a dive, a jump, a point scored, intense moments of jubilation... just before the tension falls to start again the day after.
