In The Body Double, a downtrodden young man wakes one morning to find a mysterious twin living with him. Normally the presence of a doppelgänger would turn anyone's world upside down, but in this case the two quickly settle into a routine. Together they work a thankless job, hang out, paint, go to the fair, mow lawns, fight over the blanket, upset their girlfriend, and basically continue living the same rather uneventful life the original has been living. But as the double becomes increasingly self-aware, and increasingly headstrong, more differences arise, and tensions between original and copy quickly escalate.
