Anna Lakowski

During a burglary, the owner of the apartment comes home unexpectedly, and is murdered. The cleaner, Anna Lakowski (Weis), arrives, and sees the face of one of the burglars as they flee. Undercover policeman Jakob Droste (Franckh) gets a lead on the murderers, and Lakowski is needed to identify the man she saw. Soon, however, it becomes clear that her infatuation for Derrick will be an impediment to the investigation.
