Overview
Angst (English: "Fear") is a 1983 Austrian horror film directed by Gerald Kargl, who co-wrote the screenplay with cinematographer and editor Zbigniew Rybczyński. It follows a psychopath recently released from prison and is loosely based on real-life mass murderer Werner Kniesek. Though relatively obscure, the film was acclaimed for its camera work, score, and Erwin Leder's performance. It was banned all over Europe for extreme violence in 1983.
Plot
An unnamed serial killer is eager to kill again following his release from prison, driven by a desire to see the fear in the eyes of his victims. He stops by a diner, where he is tempted to attack two girls sitting at the counter but is unable to act on this inclination in public. In a taxi afterwards, he prepares to kill the female driver but is forced to flee when the driver becomes suspicious and stops the car. The killer comes across a house during his escape and breaks in. Inside, he finds a mentally impaired man who uses a wheelchair. He mistakes the killer for his own father. Soon, the man's mother and sister arrive at the house, and the killer hides before eventually attacking them, taping the daughter to a doorknob and strangling the mother. He ties up the mother before dragging the son to the upstairs bathroom and drowning him in the bathtub.
The killer then returns downstairs to find that the mother is dead or near death. The daughter pleads with the killer to give her mother her medication; the killer complies, wishing to prevent the mother from dying before what he had planned. His attempts to revive her are futile and he pushes the wheelchair she is in into a wall in a rage.
The killer finds the daughter attempting to escape and chases her down. He stabs her to death, drinks her blood, and vomits on her (the blood having acted as an emetic). He wakes up on her body the following morning, partially undressed and covered in blood. He decides to leave in the family's car and take the bodies with him in the trunk, intending to show the bodies to his new victims to frighten them (he also brings the family's dog, alive, in the passenger seat). The killer rear-ends another car during his frantic escape, and there are several witnesses to the incident.
