Shock on the night of love: Instead of the tender hand of his neighbor Maren Wenning, the married suburban Casanova Rudi Sterzenbach suddenly feels the bloody hand of a murder victim on his face in the dark cellar. The man lying there with his skull smashed in is the speculative shark Armin Teller. Ironically, also wrapped in the banner of a citizens' initiative against the gentrification of the quarter. An initiative in which they are both active.

You: an experienced vixen with the fashion sense of a random generator. He: an Italian pretty boy who swallowed all American action films with his mother's milk. Together are Herta Frohwitter, played by Ulrike Krumbiegel, and her assistant Marco Petrassi, played by Daniel Rodic Frankfurt's new investigator duo. They successfully fight "Verbräschä" and also the quirks of each other. The first common case leads them to a wedding fair. Rosi Döpfner, a hotel manager who is no longer completely fresh, reports her fiancé Rüdiger Vogelsang as missing.
