Amy was once a party girl, but now she lives a lonely life. Helping the house-bound to receive communion in the Gravesend neighbourhood of Brooklyn, she knows the community well. When a local woman goes missing, Amy senses something isn`t right. Tailing the woman`s suspicious son, she winds her way through Brooklyn`s streets. But before she can act, he is dead. Captivated by the crime she`s witnessed and the murderer himself, Amy doesn`t call the cops. Instead, she collects the weapon from the sidewalk and soon finds herself on the trail of a killer.
