Billy Batson and the magic of Shazam!

Thanks to a magical rift, fourteen-year-old Theo Adam has returned to Earth from his banishment, but he can not remember the magic word that gives him his evil powers--so he sets out to get the information from eleven-year-old Billy Batson, the alter ego of Captain Marvel.

The villain Dr. Sivana has recently escaped from Fawcett City Penitentiary, and his plans involve a hostile takeover of the city--but Captain Marvel and Mary Marvel stand in the way.

Theo Adam is the new kid in school, but he is really just trying to get close enough to Billy Batson and his sister Mary to learn the secret word that will transform him into his evil alter ego, Black Adam--will Billy and Mary see through this ploy and be able to stop Adam?.
