Gene Autry goes undercover once again in this rather pedestrian western from Columbia Pictures. Suspecting jailed youth Dave Weldon (Dick Jones) of complicity in an army payroll heist, special investigator Autry has himself jailed. He quickly discovers that there is more to the case than meets the eye and helps Dave escape and rejoin his father's medicine show, which also includes Dave's sister Connie (Gail Davis) and the singing Cass Country Boys. Meanwhile, nasty Mike McClure (Henry Rowlands and his crew are also after the stolen money and to save young Dave's life, Gene convinces him to turn the loot over to Marshal Taplan (Gordon Jones). Among other selections, Autry and the Cass County Boys perform yet another version of Gene's signature tune, "Back in the Saddle Again".
