Translated from Spanish, the title means "left-handed person." It is also a nickname of Rafael Nadal due to him being a left-handed player.
The story is of a young boy called Lefty, a gifted marble player who lives in an urban housing complex. One day a stranger arrives claiming to know the best marble player in the world and challenges Lefty to a contest. The news sends the townspeople into a frenzy and they put all their hopes and dreams into their little hero winning much more than a simple game of marbles. With success well within his grasp, Lefty is faced with a dilemma when a corrupt local official comes along to sabotage his chances.
The music is by Paul Van Dyk and Eduardo Gamboa and the cinematography by Chuy Chavez.
