My Son, My Son, What Have Ye Done? is a 2009 film directed by Werner Herzog and produced by David Lynch, inspired by the story of murderer Mark Yavorsky. Herzog describes the film as a horror film without the blood, chainsaws and gore, but with a strange, anonymous fear creeping up in you. The film is an international coproduction between the United States and Germany.

The film begins with Detective Havenhurst driving with his partner Detective Vargas. They receive a call and drive to the scene of a murder. As they push their way through the crowd at the crime scene, they see Brad McCullam leaving with a coffee cup. Inside the house, the detectives find the body of Mrs. McCullam, Brads mother, who has just been stabbed with an antique sword. At the scene are the neighbors and chief witnesses, Mrs. and Miss Roberts. The detectives soon realize that they had just seen the murderer leaving the scene.The Robertses tell the detectives that Brad was disturbed, and had changed when he went to Peru recently. In a flashback we see Brad in Peru preparing for a kayak trip on a raging river. Back to the present time, the police have learned that Brad has taken two hostages in the house across the street. The police surround the house, and Brads fiance Ingrid arrives. Ingrid talks to Havenhurst about Brads trip to Peru, saying that Brads friends all drowned on their kayak trip, which Brad had decided at the last minute not to take part in he later claimed that the voice of God had told him to stay behind. Several more flashbacks follow of Brad and Ingrid in Brads bedroom, talking with Mrs. McCullam, looking at nearby houses, having dinner. Back in the present, Brad demands pizza for himself and the hostages, along with a car for transportation to Mexico. ........
