Jack Parker is an up and coming young hustler who wants to become part of Frank Nitti's organization. He thinks there's an untapped market on university and college campuses but Nitti thinks he's just a nickel and dimer and isn't interested. Parker has been making his own booze and selling it through Benny Angel, who hangs around the campus actually selling the stuff to the kids. Parker decides to get Nitti's interest by secretly arranging to sell wood alcohol to students and then convincing Nitti that he can make sure the stuff sold to students is clean. When Benny Angel is found dead, Ness has another reason to find the man behind the scheme.
