As Kath investigates Annie's disappearance, is she driven by a sister’s instinct, supernatural forces or the delusions of a disturbed mind? This intriguing British drama offers no easy answers, focusing on the struggle of its working-class protagonist to make sense of a possible clue she sees in a security videotape of her sister.
A move into murder-mystery territory puts the film on more secure ground, but it’s still shrouded in a mist of uncertainty, making it both braver and less satisfying than more traditional fare. Still, it has a strong cast, an eerie atmosphere and a stunning performance from Shirley Henderson as childishly seductive Kath — not to mention a killer ending.
