HairCo. is a megacorporation run by Wallace Eastman that specializes in improving people's hair. His helicopter chases after a scientist named Dr. Harrison who escapes by jumping into a river.

12 years later, a young boy named Adam Harrison the son of Dr. Harrison, lives with his mother, Shelly but keeps getting harassed by the local bullies Tony, Dale, and Garcia for being unjustly judged by other students and being the mutual crush of a kindhearted girl named Emma. Over time, he also notices that strange things start happening to him, like his feet growing bigger so his toes stick out of his shoes and that his hair growing right back over night even after his mother gave it a complete chop.
