Munich real estate firm owner Tobias Rösch is found murdered at night during his employees incentive voyage in Theo Engels's hotel VIPs cabin, which can't survive without the hefty investment he was expected to sign. Commissioner Robert Bähr finds his ex Saskia Pfeiffer, who started as waitress there, disappointing both as coldly-cooperative witness and hence 'inappropriate' date. The team finds out career - and romantic motives among Rösch's staff and on Engels's side.
