Slip and Sach work as runners for a New York brokerage firm owned by David J. Thurston, whose daughter, Carol Thurston, is romantically involved with Gabe Moreno, currently a crusading television producer. A coroner rules David's sudden death a suicide, which Slip doesn't buy into. An out-of-place matchbox on Thurston's desk carrying the insignia, "The High Hat Club," and a pair of dice serve to fortify his suspicions. Slip engages a spiel artist, Wellington J. "Buffer" McGee, to teach him, Sach, Butch, Chuck and Whitey how to beat all games of chance. "Slippery" Mahoney and "Sacramento" Sach obtain jobs at the dice table of The High Hat Club, operated by Bruce McDermott and "Countess" Margo, and bring in their friends to operate the card tables. Moreno, meanwhile, launches a campaign against McDermott, and has City Councilman John Martin aid him in his fight. Slip discovers a canceled check for $120,000, signed by Thurston, in McDermott's desk. When young millionaire Andrew Stone, III, is killed in an altercation with McDermott, the latter is exonerated after making a mysterious call to a higher-up in his racket. With the aid of Assistant District Attorney Tom Whitney, Slip and the boys bring to light the identity of the higher-up.
