Keenum is a drifter, wandering the endless desert with a closed coffin in tow. Keenum stumbles up a broken-down wagon filled with Texans who have been driven to the brink of death by their shattered leader. The men have been driven head-on into a flock of deadly birds, crazy gold-miners, and vicious rams.
In his mind, Keenum had only one choice. He must help these men find their final destination. He must protect the fallen and downtrodden. Shortly after he begins his journey with the caravan of Texans, another flock of birds attack. This time it's Cardinals, but Keenum is ready. The drifter opens the mysterious coffin, revealing a chain gun fashioned to shoot footballs. Keenum blows away the cardinals with this monstrosity of a weapon. The enemy vanquished, Keenum and the Texans ride off into the sunset.
