After being dismissed for imitating his boss's voice on radio, former Assistant District Attorney Richard Deming witnesses a store robbery and is taken captive by the criminals. Suspected of the crime, he is sought by the police, but his sweetheart, Marie, convinced of his innocence, enlists the help of two friends, a newspaper reporter and a half-witted detective. Hoping to win the girl's favor, the two go to the gangsters' hideout, encounter a violent gang war, and accidently set off a case of police tear bombs. The police, summoned by Marie, arrive just in time to save the kidnaped attorney.
