Marc is entranced by a playful exchange between two men and a woman on the street, and follows the men to their gym. On impulse he joins, but this is not a gay gym, and Marc finds himself systematically ignored. To challenge this he adopts increasingly provocative workout clothes. He is courting danger, as gym staff member Anatole tries to warn him.

But Marc doesn't listen, because one of the gym members, Orestes, appears to be showing interest. Orestes even propositions Marc in the parking lot behind the gym. The encounter is intense, beyond Marc's expectations. But it takes Marc down a path leading to captivity and utter degradation, which exposes him to unexplored aspects of his own inner nature.

Anatole rescues Marc, but needs rescuing himself from his own emotional suppression. Orestes re-enters the picture, and the dynamics of the threesome are sufficient to drive Marc to the edge of a personal abyss. He must choose between living the life of an ordinary gay man and that of a true "Sub." The BDSM relationship challenges his deepest values, but will is also feed his deepest passions?
