Newspaper reporter Nick Green tries to save sweetheart Paula Sanders' brother Dave from a murder charge, for he knows that the guilty party is George Costain, the leader of a policy game racket. Nick runs into Costain getting off a train with a satchel of the day's policy receipts, which he has recovered from Jerry Miller, one of his lieutenants who was trying to steal it. Inside the train compartment, Jerry lies dead, and although Nick suspects Costain of the crime, he is unable to prove it. Nick then steals the satchel, which sparks a game of wits between the gang boss and the reporter. Inspector Joe Keller also mixes in, as he is sore at Nick for giving "bum steer" in an effort to save Dave. Costain finally captures Paula and Nick and takes them to his nightclub, where Nick cleverly stalls for time, knowing that as soon as the gangster finds out where the satchel is hidden, his life will not be worth a nickel. Nick finally tricks Costain into going to his apartment, where Paula shoots the gang boss and his henchmen spirit him away. In the ensuing chase, with the inspector on their heels, the gangsters are wiped out and Dave is exonerated of murder.
