The Girl Next Door(2007)

In this town, murder became the neighborhood game.

In a quiet suburban town in the summer of 1958, two recently orphaned sisters are placed in the care of their mentally unstable Aunt Ruth. But Ruth's depraved sense of discipline will soon lead to unspeakable acts of abuse and torture that involve her young sons, the neighborhood children, and one 12-year-old boy whose life will be changed forever.
