In Marseille's gay community, professional bodybuilder Luc is a local celebrity, a blond Adonis with many admirers. Luc is delighted to meet a fellow bodybuilder, Gautier, with whom he soon develops a close friendship. But when Luc needs a source for performance enhancing substances, Gautier introduces him to Raoul, a doctor whose interest in muscles goes far beyond the purely professional. Luc is willing to barter his physical assets in order to obtain the drugs he wants. But what starts out as a business relationship between Luc and Raoul becomes increasingly complicated. And never more so than when Raoul decides to throw a very special party. Instead of "consulting" with his stable of juiced-up bodybuilders one at a time, the physician entertains them all at once. It's wall-to-wall muscle as the burly guests join forces to give their host a workout he'll never forget.
