The Vipers are a gang of ruthless crooks who have been looting a string of Kansas towns, robbing banks and killing citizens. They even robbed the Cottonwood Bank while James West was trying to convice the sheriff of the danger. Now the trail leads to Freedom, Kansas, where Jim and Arte must stop the Vipers before the Vipers stop them.
