Tatort: Cologne

In German with English subtitles. After a Miami drug bust goes sour, German cop Max Ballauf is sent home to be Cologne's homicide chief, and is immediately confronted with partner Freddy Schenk's professional jealousy - and the dead body of a former colleague.

A teacher recently acquitted of sexual molestation charges is killed by a bomb blast at his school. Suspicions initially fall on the victim's accuser, and Ballauf and Schenk struggle to piece together what happened when a second death rocks the campus.

While investigating a highway rest stop robbery/murder, Ballauf picks up a little Filipino boy in flight. Could he be the lead they need to bust an international child-trafficking ring?

In German with English subtitles. A woman's body is fished out of the Rhine, and the victim turns out to be an acquaintance of Ballauf's. The investigation leads to a chemical company, and the German intelligence services are found to be involved.
