Retired maverick commissioner Harry Fahrenhorst's death renders Heldt, Mario and Grün too gloomy to seriously investigate a decomposed corpse found in a large pond rather then reminisce. 'Strangled' by his necktie, pallbearer Heldt drops the casket, thus literally discovering not Harry's corpse but sand bags. Despite state attorney's instructions to leave this to another squad, they rather look into the cemetery, form where a ghost hunter points to the funeral undertaker. This turns out to receive a startling amount of nocturnal visitors, from a Gothic couple 'partying' with fresh bodies to the posthumous beautician and Harry's doting voluntary assistant in countless freelance investigations, recently including his neighbor Gregor Lenz's 'missing' wife.
