SOKO Donau (ORF)

The body of Toni Stock is found in the beautiful Sölktal. The passionate geo-cacher was killed and discovered in a cave by Lissy Schneider (Simone Fuith), who was caching herself. On Toni's mobile phone are photos showing him very familiar with a young woman. It is Eva Nusser (Sabrina Reiter), who has only recently moved back into her dead father's house. At the time of the crime she claims to have cleaned up the house, and she had nothing to do with caching. But all the more so David Lachinger (Tino Hillebrand), author of Caching and Toni's competitor. Simon (Michael Steinocher) and Carl (Stefan Jürgens) immerse themselves in the idiosyncratic world of geocaching - and make some strange discoveries in the process.
