Raw determination carried them across steep mountain trails to the lawless territory of Utah. Here brawny work gangs & rugged engineers blasted out rock-walled tunnels & laid countless miles of shining rails to link a vast continent from coast to distant coast. But soon rampaging Indians w/ rifles blazing joined unscrupulous ranchers in trying to stop the iron wheels of progress from entering this virgin, untamed land.UTAH! From the west, Chinese coolies push the Central Pacific Railroad into this barren wilderness, from the East, rawboned Irishmen drive the rival Union Pacific closer to a historic meeting in the Mormon's land. But warpainted Shoshoni wait above the mountain passes, while below a ruthless landowner sabotages America's spectacular transcontinental plan. To Toby Holt, son of legendary wagon master Whip Holt, falls the challenge of keeping law & order. Beside him, his stalwart friend Rob Martin. Behind him, a sinister stranger who threatens lovely Clarissa Holt & tempestuous Beth Martin w/ a legacy of murder & shame...while amid the rainbow canyons & everlasting hills, brave pioneers make manifest a mighty nation's greatness.
