James Everett Knight is a superpowered teenager trying to fit in with Sam, Derek, his father, Matthew, and his cousin, Noah. With the recent move to Los Angeles, California, and a new school, situations quickly become difficult for him. James is much stronger now, having his full powers back. Derek and Matthew now have superpowers, too. James and Noah must adjust to a new school and new friends while avoiding complete disaster, and he falls deeply in love with Claire Gardner, while Noah must prove himself loyal to the Knights' family - but after Grace swaps over to their side, who can they trust? With James's blood coursing through their veins, the superpowered teens, Mark and Mia Reignson, are ready to aid Max and Alexander in seeking revenge on James. If Max gets his way, hurting James will be the least of his problems, but Mark develops feelings for Noah's twin brother Bryce and reluctantly teams up with James to settle scores against Max.
