The Grey Griffins Max, Ernie, Natalia, and Harley are students at Iron Bridge Academy, a school where some students have super powers and where clockwork robots and mystical creatures exist. As their friendship is tested and they grow apart, their arch-nemesis Otto Von Strife returns with another evil plan to build the Paragon Engine. The four friends must reunite and overcome their differences to stop Von Strife and prevent his dangerous invention from being completed.
