Malaventura (1988)

Synopsis
Manuel (Miguel Molina) is a young man who feels depressed for unspecified reasons while having his dinner one night. While sitting in the dentist's chair, he witnesses the murder of a young woman thrown off the top of a building. Manuel is silent about the incident but later encounters the estranged husband and killer of the victim, and the murderer slashes Manuel's face with a knife and is arrested. The uneven story is told in flashbacks. The feature was greeted with a cacophony of boos from disgruntled viewers at the 1988 San Sebastian Film Festival. ~ Dan Pavlides, All Movie Guide
