Can evil be inherited? That's the question posed by Maxwell Anderson in his stage play The Bad Seed. This 1956 film... adaptation stars many actors from the Broadway version, including Nancy Kelly, Patty McCormack, Henry Jones and Eileen Heckart. Young McCormack plays Rhoda, a too-good-to-be-true grade schooler who occasionally exhibits a vicious streak whenever things don't turn out her way. During a picnic, one of Rhoda's schoolmates is drowned; the victim is a boy who'd won a penmanship medal that Rhoda had coveted. Nancy Kelly, the girl's mother, slowly comes to the horrible conclusion that Rhoda was responsible for the boy's death--a suspicion fueled by the discovery that Kelly, who was adopted as an infant, is the daughter of a convicted murderess.
