Based on true events, the storyline depicts a "secret investigation" of Colosio´s murder; even though it sounds illogical that the government itself ordered it, that secret investigation in deed took place, conducted by the chief of the Tijuana police, and the guy was killed in reality. In addition, it is true that there were 2 or 3 identical individuals on the crime scene when the killing occurred. There are many other well documented events surrounding Colosio´s assessination, so I´d say even though it comes to the conclusion all mexicans believe (devil-bald Salinas president ordered it), it is fantasy based on the true. (btw, the scene of the interview of "Gutierrez Barrios" is fascinating)
