A sophisticated operation is blackmailing rich and prominent visitors to Hawaii. One of the victims has told Tolliver, a private investigator, about his situation. Tolliver tells his friend that he'll work to get him free of the blackmailers. Meanwhile, a young woman has turned up dead -- which brings Five-O into the case. It turns out she was among numerous women used as bait, but she has become too hot to handle when one of the blackmail victims committed suicide. Tolliver, meanwhile, poses as a rich man to attract the attention of the blackmailers. But he has no intention of ruining the operation. Tolliver intends to take it over.
