"The Three Mesquiteers" are quietly going about their business when struggling circus owner "Nancy" (Carol Landis) shows up at their ranch thinking it is her's (she's gone and got the address wrong!). In correcting this error, the boys discover that her partners and a local bigwig are trying to swindle her out of her inheritance by offering a pittance for her late grandfather's ranch! Why do they want to so badly? Might there be gold in them thar' hills (or oil under them)? It's quite a rollicking ride, this film - plenty of chemistry on screen between John Wayne and Landis, and the story has a... lees die res.
