Shippai Kazoku

A shut-in son, a daughter who courts sugar daddies, and a cheating husband. "This family is a failure." So thinks Noriko, a housewife who is spending her days without dreams or hopes for the future. However, fate takes a dramatic turn when she impulsively kills her husband's boss. "In order for the whole family to live happily, we need to hide the body." The broken family forms a strange bond as they collude in covering-up the corpse.
