Leslie Easterbrook, Martin Kove and Michael Genovese
Harry Gillespie, book keeper for gangsters, madams, extortionists and drug traffickers, skims money from each of his clients. He escapes to a remote location in Utah with Ebony, a Vegas call girl he has befriended.
Ebony discovers Harry is being tracked down by his clients. She tries to convince him to run away to Cuba, but Harry is resigned.
Bingo, a New Orleans racketeer arrives, and tortures Harry until he agrees to return his money. They kill him.
Others come - Luke from New York, Babette from Los Angeles, and finally Michael from Las Vegas. They murder them one by one. The murders leave Harry with no hope for a better future, and Ebony with no way to escape from Harry.
