The Merchi(El Merchi)

In a violent city, one man will fight for what he believes. His nickname is the Merchi and he enters the dark world of moneylenders and debt collectors to earn quick money to try and save his ailing father. His work as a collector requires him to press the debtors hard, but the Merchi is incapable of hurting people, which causes no end of problems with Alonso, his violent and sadistic partner.
