When Amy agrees to help Hartley babysit a young neighbor girl, Scarlett, she learns that Scarlett is a huge fan of Havoc, so Amy starts to "mentor" her.
When teenage supervillain Havoc stands up to the head of the League of Villains, her family is forced to change their identities and relocate to a sleepy Texas suburb. With the help of her effervescent new neighbour Hartley, Havoc - going incognito as Amy - must somehow hide her superpowers and quell her villainous nature in favour of something she and the rest of her family have fought against all their lives: being normal.
