The 18-year-old Sarah Schubert disappeared without a trace. Her father, Mathias Schubert, starts looking for her, which is actually not unusual for a father. But Mathias Schubert is a knacki and he only has two days off. So he has 48 hours to find his daughter. In Sarah's apartment, Schubert meets a young man who is about to remove traces of blood that are apparently connected to a murder case that Ben and Semir are currently investigating. They soon realize that the murder and Sarah's disappearance are connected. The search for Sarah leads both Schubert, Semir and Ben to Daniel Lindlaub, who runs a dangerous human trafficking ring: young women are selected online, then kidnapped and sold to rich customers abroad. The Autobahncops and Schubert have little time to find Sarah before she - together with other women - is to be taken out of the country.
