An explosion at a police training camp in Afghanistan leaves instructor Saskia Harder traumatised. Surrounded by the garish clouds of smoke grenades, she realises that she has not been able to save anyone in her troop. Back in Germany, she resumes her job as a police detective in the criminal investigation department. As a precaution, she is assigned the supposedly unspectacular case of a mummified corpse that has turned up on the moor in provincial Friedland. Harder immerses herself in her work, trying all the while to repress her memories. Her investigations into unsolved missing persons cases in the area open old wounds, both in Friedland’s history and in her own past. And then a bomb from the Second World War is found and has to be destroyed in a controlled explosion. It is located of all places in front of a manor house belonging to Lorenz von Hüning, whose daughter Bea disappeared a long time ago.
