When a body if fished out of the river, Lt. Aggie Stewart of the Bureau of Missing Persons is put in charge of the case. After 10 days and having made little headway, the body is buried in a pauper's grave. As is her custom, she attends the funeral to see if anyone shows up. In this case, flowers are sent from a well-known mob-owned business. She manages to trace the woman who sent the flowers. Eliot Ness meanwhile is looking to stop the biggest shipment ever of illegal liquor worth well over $1 million. What they all soon realize is that the two cases are connected.

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.
