Elena Warnetzki 'hires' Wilsberg, for barter being penniless, to search for garbage man Thomas Warnetzki, her lover and housemate in a garden cottage the squat together while living parsimoniously from waste-collecting. Commissioners Anna Springer and Overbeck already investigate as Thomas's corpse is found in a garbage container, belonging to his employer, city-contracted waste company "Mynstermyll", where Alex was engaged as executive for PR and HR. Ekki goes undercover, garbage man being a boy's dream, as alleged experimental paroled employee mentored by 'professor' Wilsberg at "Mynstermyll", where the CEO is actually Elena's kin Isabell Meineke, who is linked to the garbage mob, which Overbeck believes to be a nightmarish Italian branch. Did Thomas stumble onto something in the garbage, what dirty side business does his supervisor Klaschka run? What about Helena's wealthy sister Olivia Haussner?
