"A crazier-than-fiction tale of three young gamblers, a Mexican drug cartel and the 1988 Kentucky Derby. - Horse Racing Nation

An inspiring true crime sports story about a filly who broke through the male-dominated world of horseracing and inspired crowds of men and women alike... along with a trio of gamblers who embark on an epic adventure... It's Seabiscuit meets Narcos, and the best non-fiction adventure and gambling story ever told.

When the gamblers unknowingly place their bet with members of a suspected drug cartel at a racetrack in Tijuana, Mexico, they must figure out how to claim their prize -- without getting killed in the process. In a heart-pounding race of their own across the U.S.-Mexico border, the trio come face-to-face with suspected killers, are arrested by the Border Patrol, and fumble their way through the riskiest bet of their lives.
