Arrived in town with a clean-up from his rich mine in the mountains, Walsh, a miner falls into the avaricious hands of Jennie Mortimer, a dance hall girl, and Slim Schaeffer, her piano-player lover. Professing affection for the rough miner, Jennie leads him into a proposal of marriage and persuades him to take her to his claim. After a few days at the miner's camp, Slim arrives. On a pretense he stays. When a rich clean-up has been accumulated, Walsh is rudely awakened by overhearing the deceitful Jennie and her paramour planning to depart with the ore. Walsh confronts Jennie with her perfidy while Slim is gloating in the tunnel of the mine. Dropping a lighted cigarette, Slim inadvertently touches off a dynamite fuse and goes further into the mine. While Jennie is struggling with Walsh to prevent him from following and shooting her paramour, they are startled by hearing an explosion. Running to the mine they find the mouth of the tunnel completely sealed by a rockslide and Slim entombed alive. Leaving Jennie with a sack of gold Walsh departs, while she tries frantically but in vain to rescue her lover. After hours of futile effort the completely exhausted woman looks up to see a buzzard awaiting its prey. She collapses.
