A pair of ex-Rough Riders, a former prostitute, a gunfighter, an aging cowboy and an English gentleman enter a 700-mile horse race through the Southwest desert in 1908.

In 1908, a newspaper organizes an endurance horse race through the desert: 700 miles to run in a few days. Nine adventurers are competing, among them a woman with unclear motives, a Mexican, an Englishman, a young gunfighter, an old cowboy and two friends from their days with the Rough Riders in Cuba, Sam Clayton and Luke Matthews - all matched against a thoroughbred backed by the race's sponsor. These individualists will be challenged to respect each other as the competition becomes increasingly brutal and strenuous.—Yepok

In 1908, the popular Western Post newspaper sponsors a demanding cross-country horse race, attracting a motley crew of ambitious contestants against a thoroughbred backed by the publisher. With a tempting $2,000 prize, the bold competitors - including plucky former prostitute Miss Jones; ex-Rough Riders Luke Matthews and Sam Clayton; a Mexican vaquero with a terrible toothache; English gentleman Sir Harry Norfolk; aging cowhand Mister, and the arrogant gunfighter Carbo - will have to endure 700 miles of unforgiving desert and rugged terrain. The race is on. Who has what it takes to bite the bullet?—Nick Riganas
