What is K-12 about?
Cry Baby, a strong and sensitive girl, is sent off to a disturbing sleepaway school that’s hidden underneath a grandiose façade. Luckily, she has a sweet and unapologetic best friend who sticks up for her when she gets bullied by the other students whose brains are under control by the Principal and his wicked staff. With the help of the magical friends they meet along the way, as well as an Angelic Spirit Guide, they are able to gain the strength they need to fight off the school’s belligerent patriarchal conditioning.
