Republic's Trucolor "special" Susanna Pass stars
Roy Rogers and
Dale Evans, King and Queen of the West. Rogers plays "himself," while Evans is cast as female doctor Kay Parker. The villains this time around are trying to force a fish hatchery owner out of business so they can drill for underwater oil. The film's action content never impedes its musical highlights (and vice versa); among the vocal contributors are Estrelita Rodriguez (who figures prominently in one of the cliff-hanging action setpieces) and Foy Willing and the Riders of the Purple Sage. Susanna Pass represented the on-screen reteaming of Rogers and Evans, after several attempts by Republic to link up their Number One cowboy star with other leading ladies. Surprising, Rogers isn't teamed with a comical sidekick, though Estrelita Rodriguez is admittedly pretty funny as a flirtatious senorita. ~ Hal Erickson, All Movie Guide
