On a beautiful summer day in Destin, Maine, Ellen Chambers watches helplessly as her beloved teenage daughter Moreen marries the worst possible man. Ellen–whose own marriage is crumbling, and who is desperately in need of a friend–knows her new son-in-law has violent tendencies and is certain to make Mo’s life hell. As she wonders wistfully in silence if it’s possible to get away with murder, a handsome young stranger, an uninvited wedding guest, leans in to her and whispers, "Anything’s possible."
