In the city of Westville, ice cream-shooting 12-year-old Super Jake is having fun as the sole hero. That is, until his world turns upside down when his younger brother, 11-year-old Kenny, receives his own unique ability: controlling his hair in extraordinary and unpredictable ways.

As Jake grapples with not being the only superpowered kid in the family while trying to make it as an investigative reporter, the brothers navigate their sibling rivalry. Their bond is put to the ultimate test when a sinister new villain emerges. Muscles, a P.E. coach with the ability to transform into a giant red monster, threatens the city with his twisted ideology: convincing young boys that physical might trumps character and heart.

With time running out, Super Jake and Kenny must unite, combining ice cream power with hair-raising tactics. But can they put aside their differences in time to understand the true meaning of strength? Will they discover that working together is the only way to save the city?
