Singing cowboy Gene Autry stars in this formula western as Gene Autry (so far, so good), who teams up with his buddy Frog Millhouse (Smiley Burnette) to investigate a series of accidents which have stopped construction of a dam being constructed by Sam Flint (George Baxter) and claimed the lives of much of the work crew. The progress of the dam is also thwarted when Bull Dural (George Cheseboro) and his gang attempt to steal the payroll; Gene and Frog suspect Bull may also be behind the deadly dirty tricks campaign before discovering he's just a pawn in a bigger game. Autry finds time to sing five tunes during the proceedings, inclusing the classic title song.
