Forgotten (1999)

Ben Turner runs a second-hand bookshop in a lovely English village, lives in a bed-and-breakfast run by his devoted wife, and has a perfect 7-year-old daughter. But the cracks in this idyllic world begin to show the day a local girl is murdered and the enigmatic Rachel Monroe appears. Rachel is convinced that Ben is the killer of her daughter who died 20 years earlier. She confronts him and demands to know where the body is—or else.
