No manches, Frida

It's the story of Zequi, a recently released bank robber who goes back to recover the stolen money buried by his dim-witted accomplice before going back to prison. They return to the site only to find that a tall Frida Kahlo has built a gym with the loot. To get the money, they pose as substitute teachers at a school that can't measure up to the teachers at any other school. Zequi walks in ready to lay down the law, but he quickly realizes that life on the inside may have been easier to handle than a school full of wild, rebellious teenagers.
