Stuttgart's best-known, colorful LSBTTIQ bar owner, Samuel Hofer, is beaten to death outside. The community protests against the presumed hate crime, but the team must also consider Hofer's personal adversaries. Anton Zapf, who had to sell him the bar "Streusand" after the rent was doubled, openly swore revenge, committed repeated vandalism and his dog's hairs are found on the victim. Samuel's unrealistic third world activist Helena is broke, rejected by their parents, move din with Samuel, yet he planned to sell out and start a new life without her. DNA also traces to German-born Khales Karimi, youngest son of an Iranian refugee with terminal cancer, and closet-gay, the only threat to his apparently bright future, hence big brother Yunis's pride.
