Mustang Millionaire

Mustang Millionaire premieres Saturday, Dec. 14, at 10 p.m. ET/PT, on Nat Geo WILD. The three-part miniseries brings five mustang-crazed cowboys and cowgirls together as they come from across the country to give it all they've got for their share of the million-dollar prize. We'll see them bid against some of the best horse trainers in the world, in the hopes of picking the one wild mustang that will give them the best competitive edge. (Source: Nat Geo WILD)
