Detective Anna Badosi is in a jewelry shop and finds owner Enno Patitzsie fatally shot in the back room, shots at a masked, armed robber and wounds him, while his female accomplice escapes. David Schrader's fate shakes Anna's confidence enough to reconsider her parents Renate and Lozenzo Badosi's initially rejected plan to start an inn in Italy. The police team, to Rico's annoyance joined by fresh rookie Nelly Kienzle, investigates David's claim he found Enno dead. The jeweler's son and heir, Thomas Patitz, left the family business after a row and started an Internet firm. Enno cheated systematically on his wife Antonia Patitz, who knew. The second robber is identified as Ina Schrader, elder sister of teen David Schrader, who remains in mortal danger. They were desperate for cash after buying a small garage. She's arrested after trying to free her brother by taking a doctor hostage and claims Enno Patitz hired them for insurance fraud. Rico Sander finds the final trail.
