Heldt can't prevent young Sabrina Bergmann being pushed down a metro stairs, into IC. Heldt is determined to find the culprit, convinced unlike Grün, she was a deliberate target. Security video footage only shows a FC-Schalke-logo on the fiend's hoodie. One such is seen in the car of her overprotective, choleric ex-con brother Michael, who is most furious about her relationship with older ice parlor partner Benjamin Schmitz. Heldt sees them row even at her sickbed. Sabrina demanded distance from both, having been in her brother'' custody after an abusive childhood and foster care. Laura Schmitz, Benjamin's ex-wife who co-owns the ice parlor, also has a jealousy motive. Michael is in anger management therapy and the club badge is found different. Grün checks out Sabrina's employer, fancy hotel-restaurant "Goldene Taube" manager Gerhard Kaiser, whom she threatened with sexual harassment charge, as other men before, and hotel supervisor Stefan Grotte, whom she blackmailed for stealing luxury wine. Laura Schmitz was jealous of Ben's younger lover. Finally Heldt sets a trap.
