Julie, the seemingly innocent blonde, finds herself alone at home, her husband away on business. Bored and horny, she begins to explore her desires. She starts by masturbating, her fingers delving into her wet pussy, imagining her husband's touch. As she grows more daring, she records herself, her moans filling the room. She sends the video to her husband, but in a moment of carelessness, she also sends it to her husband's colleague. The game of cat and mouse begins as Julie's secret life is threatened to be exposed.
