A jewelry store has been robbed, and the theif has escaped. It’s Joe Friday’s job to find him. Friday, and partner Frank Smith question the store employees, and look for clues. Fingerprints, and stains that prove to be blood.
More interviews with suspects, and a tip from another of the police departments gives Friday a good trail to follow. An ex-con with stolen goods takes Friday further down the trail of stolen goods. A trail that leads to their man.
Joe Friday gathers hard evidence along the way that will seal the fate of the robber.
