Phoebe and Max Thunderman are twins who, although they have opposite personalities, share a common secret. The teens, along with their parents and younger siblings, are superheroes. But the family must keep the superpowers under wraps and live a normal life. Phoebe and Max have the same powers -- freeze breath and the ability to move objects via telekinesis -- but use them in opposite ways. Good-natured Phoebe tries to do the right thing, while troublemaker Max wants to become a supervillain. Little brother, Billy, is able to move at superspeed while little sis, Nora, has laser beam eyes. Dad, Hank, can fly and has extraordinary strength, but mom, Barb, is able to generate lightning from her hands. This family wants to lead a normal life? Good luck with that.
