Rico's gang members Creeper, Harry, and Red are also sent to jail with Gray.

When Gray's fiancée even believes Johnny is guilty, he becomes angry and a difficult prisoner.

Gray is eventually put in the same cell as Cain (Jack La Rue); who is the head of a gang that's planning a prison break.

Frank Sanders (Milburn Stone) is a new warden at the prison, and he eventually earns Gray's trust.

While working in the gardens, Gray meets Amy Duncan (Joan Woodbury), who is the daughter of one of the prison guards.
