CHAOS (2000)

A man gets involved in a kidnapping scheme with the wife of a wealthy businessman. She lets herself be tied up and confined in his house while he sends the ransom demand. When he returns home that night, however, he finds her laying dead on the floor. In a panic he buries her body deep in the woods and tries to return to his ordinary life. One day, he thinks he spots her walking down the street. Is his mind playing tricks on him, or has she somehow returned from the grave?
