A contract murder is being carried out in the luxurious Tropical Bay hotel. The victim is casino owner and member of the local mafia family Max Vernon. The killer, the young beauty Lily, is very smart and experienced. However, having killed Max in the hotel, she makes a mistake: it will not be easy for her to escape retribution. The hotel owner's security guard, the deceased's angry brothers, detective Susie Pine, conducting her first investigation, and former Chicago policeman Joe Riley, who has an old score with the criminal, are immediately on her trail.
