Directed by prolific Mexican filmmaker René Cardona, LA MULA DE CULLEN BAKER stars Rodolfo de Anda of the legendary filmmaking family. The West was never tougher than for Cullen Baker, who rides from town to town on his mule and is mocked the whole way. But when he spies a group of soldiers sporting a new type of revolver, he sees his opportunity for revenge on the world that has ridiculed him. Stealing guns from a pair of the men, he is chased by the rest and murders them. Now, with more guns than he can use and a fury born from an arduous past, Baker becomes an outlaw, robbing banks and shooting anyone who gets in his way.
