The gas station attendant is shot dead in a gas station in Mainz – the second and this time deadly attack within two weeks. The only witness to the crime is the blind law student Rosa Münch (Henriette Nagel), who still lives with her parents and longs for a life beyond her father's overprotective control. Ellen Berlinger (Heike Makatsch) and Martin Rascher (Sebastian Blomberg) investigate on the trail of the two perpetrators and follow the clues of the blind man: the smell of an expensive perfume, the voices of suspects, the details heard and felt by Rosa at the crime scene. The inspectors want to put the vulnerable Rosa under police protection, but the young woman refuses. On the contrary, when a young woman seeks contact with her,whose voice sounds familiar to her, she keeps it to herself. Ellen Berlinger and Martin Rascher suspect that Rosa knows more than she says - maybe even knows the perpetrators, likes them, finds them attractive... gets involved in something that she doesn't tell them. The investigators have to continue investigating without her support and resort to unusual methods to prevent further deaths.
"Tatort: Blind Date" is the second joint assignment by Heike Makatsch and Sebastian Blomberg as Commissioners Berlinger and Rascher in Mainz. Author Wolfgang Stauch and director Ute Wieland involve them in a case that deals with self-determination and a longing for risk, with different types of feelings and the question of when things get serious.
