Gangster Vincent 'Mad Dog' Coll is out to get revenge on his arch-enemy Dutch Schultz just about any way he can. After his attempt to kidnap Schultz's bookkeeper Lefty Gallagher goes awry, Coll decides to kidnap a horse Schultz has made a big bet on for the Kentucky Derby race that is still several months away. Coll comes by his nickname easily and will go to almost any lengths to get at Schultz. Ness and his men use that to their advantage.
