Eda (Şahika Tekand) and her husband İdris (Levent Özdilek) present an intellectual and harmonious exterior, but their marriage suffers from sexual frustration and İdris's alcoholism. When İdris leaves on an extended business trip to Paris, Eda goes out with their mutual friend, painter Erdal (Mahir Günşiray). Following a night of drinking, Eda and Erdal engage in a passionate sexual encounter. Though Eda initially regrets the one-night stand and tries to end it, Erdal becomes obsessively persistent, leading to a volatile extramarital affair that degrades into physical obsession and psychological manipulation behind İdris's back.
