Three young children await after school for their mother to return home from work. A mysterious knocking on the apartment door spurs their curiosity to entertain themselves by playing a sick joke on their mother upon her return. Before the mother can greet her children she gets word from her mother that her violent ex-husband has been seen around the apartment, looking for his son Joshua. As the already alerted mother walks in on her children's sick prank, the ex-husband takes advantage of the moment and has his violent fantasy in the palms of his hands.
