Yet Katja's hope that the murderers receive their sentence in court is shattered. Following a harrowing trial, in which Nuri's best friend Danilo serves as Katja's lawyer, Edda und André are acquitted for want of evidence. Katja is devastated, but soon her desperation gives way to an urge for vigilante justice.
