While Gwen and Grandpa Max deal with problems at space, Ben has a problem of his own. Ghostfreak returns, and this time, he plans take over the world by shrouding it with darkness and radiate it to create his minions. Ghostfreak finds that Ben has learned a few tricks over the last time they met. With the mummy, Dr. Vicktor, the alien wolf, and his own family to deal with, would it be enough to fight against him? It will be, only if Ben learns the meaning of working together.
