A woman in a leotard is bound, tormented by a man who revels in her helplessness, while another woman in a leotard obediently follows his commands without resistance. They exist in a dark, twisted world far removed from normal life, treating women like pets. The woman refers to herself as the "keeper," dominating her lover while the man submits entirely to her will. Both women are bisexual, using whips, dildos, and chains to satisfy their desires and assert control over other women. Hidden as the secret of the rhythmic gymnastics club, these cruel abuses thrive in shadows untouched by light. Even as the man becomes her lover, she remains the absolute master, reducing him to a mere subordinate. As long as this relationship continues, their fate will inevitably spiral into darkness and despair.
