The hero of the adventure series "La Cabeza de Joaquín Murrieta" is known worldwide as the "Mexican Robin Hood." Honor, conscience, and truth are more important to Joaquín Murrieta than money, fame, and personal ambitions. He finds himself outside the law, but his true goal is noble, not criminal. One day, he meets his namesake, Joaquín Carillo, who is also on the run and literally walking a tightrope. The men join forces to rise up against their common enemy - the bandit and assassin Harry Lava.
