The dramatic true story of two brothers living parallel lives on either side of the U.S.-Mexico border-- and how their lives converged in a major criminal conspiracy. Jose Trevino was a devoted family man working as a bricklayer in Texas. Back in Mexico, his younger brother Miguel was ascending to the top ranks of Los Zetas, a notoriously bloody drug cartel. One day Jose showed up at a quarter-horse auction and bid close to a million dollars for a horse, which caught the attention of an eager young FBI agent named Scott Lawson. Lawson enlisted Tyler Graham, an American rancher who would eventually breed Jose's champion horse-- nicknamed Bones-- to help the FBI infiltrate what was revealing itself to be a major money-laundering operation, with the ultimate goal of capturing the infamous Miguel Trevino.
