After decades of wearing a cape and protecting the city of Seaholm, World War Two veteran hero Mel is forced to retire and train her replacement. The new cape in town is Jessie McGrath, a teenager who is different from Mel in almost every way. Together, they chase the other super-types from Mel's past, leading to a brutal confrontation with the monster called Sawtooth. The superteen hero Versema is also tested by a hero called Atomic Butterfly, a villain called Rosevera Archyle, and an ex-minion or two.
