A recently paroled bank robber (Omar Chaparro) returns for his buried loot only to find that the Frida Kahlo High School has built a new gym on the land. His new plan: retrieve it from the inside, while disguised as a substitute teacher. Little does he realize that this high school is more unruly than prison was. (“It’s like The Treasure of the Sierra Madre meets Kindergarten Cop,” an astute friend noted.) A lot of the jokes in this goofy Spanish-language comedy revolve around Chaparro throwing, dropping, and flinging various teenagers around.
