In the play, an eight-year-old Rhoda is the only child of Kenneth and Christine Penmark. Kenneth Penmark goes away on business, leaving Christine and Rhoda at home. Christine begins to notice that Rhoda is acting strangely after one of her classmates mysteriously drowns, and eventually makes a horrible discovery: Rhoda killed the boy, and will almost certainly kill again.
