The Last Cowboy is a documentary-competition from Academy Award-nominee Taylor Sheridan chronicling the elite Western horse riding competition of horse reining. Eight men and women face off against one another as they guide their horses through a precise pattern of circles, spins and stops.

Sheridan ups the ante as he launches the "Run for a Million," which is an arena-based reining competition with a prize worth $1 million that takes place at the South Point Arena and Equestrian Center in Las Vegas.

Fans of horse competitions get an inside look at the daily lives of these horsemen as they train and make preparations for the big event which will close out the series. Only one champion can come out on top to claim the $1 million prize.
