Charlotte Lindholm has to solve the murder of the security guard Sven Gutzkow, whose body has been buried in the salt heaps of the Gorleben exploratory mine for six months. Soon she is investigating in a volatile milieu. The head of the operating company of the nuclear interim and final storage facility, Kasper, has been blackmailed for some time. Gutzkow's colleagues Augenthaler, whose home is still under construction, and the geologist Sandmann are under suspicion, and what does the long-serving anti-nuclear activist Welany know? Charlotte and her colleague on site, police chief Jakob Halder, turn Wendland upside down with their investigations. They are observed at every turn. The result: a locker key, a supposed voice from the afterlife and another corpse.
Charlotte is warned by her friend Belinda that this is a size too big for her. But Charlotte is undeterred. When she finds out that Gutzkow met Ahmadin, the Spanish terror accomplice, before he died, the hot lead leads her to Barcelona. There she stabs into a wasps' nest and puts herself in extreme danger..
