“K-12” is a theatrical film directed and written by Melanie Martinez. It follows the same name of Martinez’s sophomore album K-12.

The story is about Crybaby (Melanie Martinez) and her best friend Angelita (Emma Harvey) who both get sent off to the disturbing K-12 Sleepaway School, hidden underneath a grandiose façade. As the two move through their early stages of life and slowly grow up, they gain new friends and embark on a mission to take down K-12’s oppressive school system.

The film premiered in Los Angeles, California on September 3, 2019, and was chosen to display in select theatres on September 5. Martinez released the full film on YouTube one day after its premiere.
