Caitlin goes to her mother to help understand the meta-human powers growing inside her. Meanwhile Barry tries to convince Julian to allow him to help investigate a new human meta-attack on Central City.
As Barry helps his daughter, Nora, become a better speedster, he and Team Flash also track down a meta stealing high-tech weapons, only to cross paths with a new foe named Cicada, who is hunting the very same meta with nefarious intent.
