A mine cave-in traps Simon and Quince, after Rowdy sent them in to check out the shaft's stability, before the drive ventures through the ravaged mountain pass adjacent. In the quarry, a bear-like creature attacked Quince, then Simon's gunshots at the beast caused the cave-in. Cowhands Ed & Jerry, who aren't pulling their weight on the drive, come forward with a way to free the drovers before they perish from gas. Ed already scavenged gun-jell from the abandoned mine camp, and claims to know how to blast the rubble away - but only for a $500 fee. With no other help close enough, trail boss Rowdy agrees.
