"Kommissar Taler" is about the young and dynamic inspector Christian Taler (Alexander Knaipp) and his feisty new Tyrolean assistant, Angela Reiter (Tina Winkler) and how these two different people try to solve an eerie murder in a small Austrian city. The city of Traun is home to a legend, a legend where a farmer tricked the devil by sacrificing himself to save his daughter as payment for a dark pact. Present day, the same date: there is another dead man hanging in a tree - is the devil back in Traun? Christian and Angela, both trained in different deduction methods want to solve the mystery their own way. Was it the devil? Or perhaps a young Turkish rowdy who was having a party in the forest the night before? Or someone else from the victim's past or present? Only together can Chrisitan and Angela solve the crime, but they can't seem to see eye-to-eye - the devil's in it.
