Nick Acropolis has created a vast network of bookies and is the king of the numbers racket in the greater Chicago area. His problems start when he discovers that Louis Manzak, his wife's brother and the manager of one his betting parlors, has skimmed $200,000 of the proceeds. Were it not for the family relationship, Nick would have had him killed but rather he gives Louis 48 hours to come with $50,000 as a down payment on what he owes. His sister lends him half of that amount but his attempt to borrow the rest from someone else leads to disaster.
