Marshal Corrigan (Ray Corrigan) turns up in Sundance and sets up a shooting date with the Mesquite Kid (I. Stanford Jolly) whom he promptly despatches but really he is in town to investigate the mysterious Bolton (John Merton) whom he thinks is up to no good but isn't the real leader of the gang. When Bolton's men blow up a mine payroll wagon Corrigan is thought to be killed. However he is still alive and with the help of his fellow Range Busters (John King and Max Terhune) investigate the gang and uncover the real mastermind.
It is a rather straight forward but enjoyable Western, simple cowboy adventures with a ventriloquist dummy (yes that's right Max Terhune's dummy Elmer).
