Singer Tony Martin plays the non-musical title role in United Artists' Quinannon, Frontier Scout. Sent on a top-secret mission by the government, Quincannon tries to find out who's been selling repeating rifles to the Indians. The culprit turns out to be an old friend of the hero--and, for plot purposes, the brother of heroine Maylene (Peggie Castle). Throughout the film, Tony Martin appears uncomfortable and uncertain, a bad combination when you're dealing with taciturn Indians and renegade whites. On the plus side, Quincannon, Frontier Scout is gorgeously photographed on location in the Utah desert.
