The Hammer Killer - trail of blood from a police officer

In the mid-1980s, a mysterious series of murders spread terror in the Swabian province. The perpetrator ambushed his victims near lonely forest parking lots, shot them in the face in order to seize their car to rob small bank branches. There, he knocked a hole in the security glazing with a sledgehammer, sticked out his pistol and demanded cash. After the second attack he was called "the hammer murderer". The police were under enormous pressure, they didn´t want to admit what was quickly becoming apparent: the perpetrator comes from within her own troups. Shortly before the spectacular series of crimes was solved, the man killed his family and ultimately himself. The documentary traces the life stages of the murderer, his path from a humble man to a serial killer and bank robber. Friends, colleagues, journalists and police officers were interviewed, possible motives, speculation about the psyche of the killer, but also the search of the police, their mishaps and helplessness.
