Cripple senior Ingrid Petersen was skull-smashed as if in a failed robbery, which seemingly yielded no loot of value. her son Philipp Petersen now reconsiders her dismissed claims since months, according to his partner a sign of dementia, of receiving anonymous calls and objects being moved around the house. Searching from a possible intruder and/or murderer, the team discovers in neighbor Johanna Röhl's home a rare admiralty clock identical to the one Philipp Petersen confirms being stolen from Ingrid and come on the trail of systematical insurance appraisal errors and counterfeiting.
