As the Union Pacific and the Central Pacific built the rails that would meet to unite a vast nation, Wind River became the newest railroad in wild Wyoming Territory - a town ripe for trouble and a special brand of justice.

Big trouble is brewing in Wild River. The Irish are up in arms as the Chinese arrive from California to work on the railroad and the friendly Shoshone stand accused of stealing cattle. Wild talk of gold sends settlers rushing into the Wild River Mountains as the army arrives to protect the railroad and strong-arm the Indians into honoring their treaties.
As enraged railroaders launch a disastrous attack against The Shoshone, and the cavalry thunders toward a catastrophic confrontation, only Marshal Cole Tyler and his deputy Billy of saboteurs hell-beat on lighting a fuse that will set off a bloody massacre.
