The beautiful western scenery of northern Wyoming is the backdrop for The Invasion of Johnson County, based on the actual Johnson County War. The battle was also known as the War on Powder Creek, fought between large cattle ranchers and homesteaders in 1892. Bill Bixby (The incredible Hulk) stars as a free-spirited Bostonian Sam Lowell, who arrives in the frontier and teams up with George, a crusty Wyoming cowboy (Bo Hawkins/Dynasty) to stop a land baron's attempt to drive out a group of small ranchers and take over their property. M. Emmet Walsh (The Wild, Wild West) co-stars.
