Mysterious drifter Tae-suk enters other people's lives as easily as he breaks into their unoccupied homes.

But when he sneaks into a sprawling mansion, he discovers a beautiful, lonely wife named Sun-hwa, trapped in a loveless marriage. Without saying a word, the pair begin an erotic game of cat-and-mouse, until her abusive husband returns home, unleashing a shocking burst of violence. Tae-suk defends Sun-hwa with the aid of her husband's golf club. The lovers run away together finding domestic bliss inhabiting strangers' homes. Later, when Tae-suk is framed for a murder, even prison walls can't keep them apart for good.
