A spin-off of the Wire, this is another racing con, sometimes known as The Syndicate. The Roper finds a Mark and tells him he knows an Inside-Man, someone in the know, a big winner. Bets are placed and paid off. Since the Inside-man knows the races are fixed, he can always pick a winner. But the Syndicate fixing the races is under investigation. There’s only time for one more go ’round, so it should count, big money.
Much like the Wire, the Mark is duped of his money with some mix up: told to put the bet on ‘place’ instead of ‘win’ or with the ring/betting area getting busted by cops.
