This movie involving the drug trade has good writing(the prolific Carlos Valdemar, best known for the horror flick, Ladrones de Tumbas) and good overall production values with nice scenic locations. In fact most of the filming is outdoors. The music score is fine as well, with some emphasis on the electric guitar. A notice should have been handed to the cast, though, stating "no acting required". Augustín Bernal shouldn't have agreed to do the film as there is not much for him to do as one of 3 henchmen. Patricia Rivera was in the first few minutes(it took 2 minutes for a shootout and explosion) and then didn't appear again until the half hour mark. She got to show off her pretty legs in the film, but other than that her fans don't have too much to look forward to. The story starts out in Monterrey, N.L., then briefly switches to Colombia, then to Mexico City. The brunt of the plot line involves the law, Fernando Almada and Toño Infante(nephew of the great Pedro Infante), transporting the drug king's sister(played by Patricia Rivera) to a new location with brother and company trying to intercept them. Standard fare with the usual amount of violence, but they do come up with a new variation at the climax. Highlights include Fernando using an old car as target practice and later going on a slapping spree first with his nephew, then with Patricia. She, on the other hand, tries to seduce Fernando 1st(who wears a winter coat in the hotel while Patricia wears a bathrobe), then, getting no result, has a little better luck with his partner. When the criminals have their car smashed by the good guys, they don't steal another one but pay cash instead for one from a nearby resident! And the criminals at one point use 2 motorcycles for a chase scene. The movie clocks in at a brisk 84 minutes.
