Rhoda, The Bad Seed As the film's title suggests, the main subject of the movie is a bad seed. In fact, she's an evil seed. The seemingly sweet and obedient 8-year-old girl named Rhoda turns out to be a sociopath who remorselessly kills a boy and an elderly lady in order to get what she wants. Her heinous actions prompt her disturbed mother to uncover unsettling secrets about their family history. Image Source: Everett Collection
