An unexpected, aggressive knock at his front door startles a young man, Mark (Ricky Spanish). He opens to find his neighbor, Adriana (Sheena Ryder), appearing distraught and seeking shelter from her spouse Charlene (Lily Lane). Adriana elaborates that a heated dispute with Charlene, resulting from a certain act committed by the latter, led her to seek refuge. Curious, Mark inquires about the cause of the dispute but is interrupted by Charlene pounding on the front door. It transpires that the spouses' disagreement stemmed from Adriana's allegations of infidelity against Charlene. Charlene portrays herself as an innocent party wrongly accused, but Adriana implores Mark not to allow her entry. Adriana insists that Charlene is merely trying to manipulate them and guides Mark further into the house, claiming to protect him from Charlene's deceit. Shortly thereafter, Adriana and Mark find themselves in another part of the house, distinguished by a large window. She applauds Mark for his support. Mark attempts to downplay his role, stating he's happy to help, but his gaze on Adriana betrays his delight in receiving praise from an attractive woman. Adriana then bemoans the precious time she has wasted...time that could have been spent pursuing anything and anyone. Instead, she chose to dedicate years to a duplicitous individual who ultimately betrayed her. Suddenly, Charlene emerges outside the window, pounding on the glass and accusing Adriana of overreacting. In response, Adriana mocks her by highlighting Mark's superiority over Charlene. In a bid for revenge, Adriana entices Mark into a sexual encounter while a helpless Charlene watches from outside. As Mark passionately takes Adriana from behind, she presses her bare chest against the window, providing Charlene with a spiteful spectacle she will never forget.
