Oregon, 1851. Hermann Kermit Warm, a chemist and aspiring gold prospector, keeps a profitable secret that the Commodore wants to know, so he sends the Sisters brothers, two notorious assassins, to capture him on his way to California.
In 1896, Jeff Webster sees the start of the Klondike gold rush as a golden opportunity to make a fortune in beef...and woe betide anyone standing in his way! He drives a cattle herd from Wyoming to Seattle, by ship to Skagway, and (after a delay caused by larcenous town boss Gannon) through the mountains to Dawson. There, he and his partner Ben Tatum get into the gold business themselves. Two lovely women fall for misanthropic Jeff, but he believes in every-man-for-himself, turning his back on growing lawlessness...until it finally strikes home.
In order to make Tug Cardwell (William Phipps) sign over his rich gold claim to them, John Avery (Robert Shayne), Gypsy Avery (Veda Ann Borg) and Jackson (Marshall Reed) hire Bob Rankin (Douglas Fowley') to kidnap Tug's sweetheart Jane Whipple (Elaine Riley). Rankin hides Jane and then demands half the mine from the other crooks. Dave Saunders (Tim Holt) and Chito Rafferty (Richard Martin), friends of Tug's, find Jane and taker her to safety. The conspirators then shoot Rankin, capture Tug and force him to take them to his claim. Dave and Chito are close behind.
