The Senate decides to settle the fertile land of Wyoming. Before moving in the settlers, they send a committee of four scientists, led by Lucky Luke, to survey the territory. One senator is strongly opposed to this project and determined to sabotage the expedition.
However, the Senate overlooked one important fact: the land territory is home to the Cheyenne Nation, who are determined to defend their land.
