Detectives Grijpstra and De Gier are sent to investigate the case of a man who apparently hanged himself in a center for oriental meditation. It is ruled as suicide and the case seems to be closed, but the same night there is an attempted break in. The investigation hits a dead end and everyone involved is a suspect. Based on the book "The Corpse in the Haarlemmer Houttuinen” by Jan-Willem van de Wetering.
