The 15-year-old Jessica Day moves with her family to Bixby, Oklahoma, after her mother is employed at a high-tech aerospace company.

Soon after the move, Jessica awakens to find time frozen and rain stopped in mid air.

Leaving her room, she finds that her family is frozen and the only other living thing is a cat, which leads her out of her house.

After flying for most of the hour the pair are chased by a darkling and narrowly escape, only to be arrested by policemen enforcing Bixby's eleven o'clock curfew.

However, they are all late and rely on Jonathan to fly them inside the protection, which causes Rex to get jealous and Melissa to get disgusted and angry.

As the defenses are breached, Jessica realizes that her watch is still ticking, which implies that her ability allows her to use technology in the secret hour.
