No Manches Frida (2016)

Storyline

After his release from prison, bank robber Zequi sets off to recover the stolen money that was buried by his dizzy accomplice. He's horrified to learn that a high school gymnasium is now standing over the site where the loot is stashed. Needing to infiltrate the building, Zequi lands a job as a substitute teacher for a group of wild and unruly students. As the ex-con tries to lay down the law, he starts to realize that life in jail may have been easier than trying to deal with rebellious teens.
