Die Chefin S02E03 - Sperrbezirk

The kidnapped Moritz Helmes, son of a wealthy real estate agent, is found murdered. Apparently, Moritz' father Christian Helmes was to be blackmailed, but then the boy managed to escape. The tracks lead chief inspector Lanz to Munich's red light district, with which her colleague Paul Böhmer maintains close contact. Böhmer has a particularly close and intimate relationship with the prostitute Johanna. Johanna asks him to take care of the young prostitute Tereza, who seems to be involved in an illegal matter - without informing his colleagues. As it turns out, the submerged Tereza is the last to see Moritz alive.
While Böhmer becomes increasingly entangled in a conflict of loyalties – observed suspiciously by his boss – Vera Lanz not only discovers the kidnappers, but also a connection between Christian Helmes and Tereza. This leads the commissioners to a murder case that was covered up a few years ago. When Johanna then disappears without a trace and Böhmer finally finds her dead, Vera has a lot to do to protect her colleague from making a big mistake.
