Rocky Lane is once again a government investigator sent to check on a mercury mine where reports of stolen quicksilver is reaching government ears. In fact the mine is under the supervision of Army Lieutenant Myron Healey because it is the time of the Spanish American War. Still even with Healey and soldiers there, the stuff is being siphoned off.
Someone is also trying to bankrupt Eddy Waller who runs the stagecoach line and has the mail contract. These outlaws are just interested in destroying his stagecoaches and leaving him destitute to force him off the property that he owns adjacent to the mine.
Perennial western villain Roy Barcroft does his thing in Desperadoes' Outpost and Lyle Talbot is on hand as a scurvy banker.
There is a method to the outlaw madness and the only clue I'll give you western fans is that mercury in its natural state is a liquid. Take it from there.
