Tatort: ​​Ätzend (Tatort: Ätzend) (translated)

Ätzend is a German television film from the long-running crime series Tatort, first broadcast on 15 November 2015 as the show's 962nd episode. Directed by Dror Zahavi from a screenplay by Stephan Wagner and Mark Monheim, it marks the second case of the Berlin investigative duo Rubin and Karow.

In its opening seconds the episode uses black-and-white flashback images to reference the team's first case, Das Muli. This horizontal storytelling, in which plot threads stretch across multiple episodes, was unusual for Tatort and was carried over into the following case, Wir – Ihr – Sie. The 87-minute production by Rundfunk Berlin-Brandenburg and Wiedemann & Berg Television features Meret Becker, Mark Waschke and Maryam Zaree among its cast.
