Lizzie and Tyler Warren return to their failing school, Hazelbrook, only to find it's been transformed the table-topping Hazelbrook Academy. How? Under the strict leadership of the mysterious Headmaster.
When Lizzie falls under the Headmaster's hypnotic powers, a new ally enters the scene: school football star Ethan Prendergast. Ethan, too, has noticed something weird happening at Hazelbrook Academy and wants her help to stop it.
Accidentally freeing Angelika from the Headmaster's control, Lizzie and Ethan hatch a plan to learn the Headmaster's real plans while avoiding the new drones.
While the Headmaster goes off to visit other schools, the gang enlist the help of a reporter to expose the truth. However, this reporter knew Mrs Maron in her old life, when she was a campaigner for human rights - can she break through?
Lizzie is at breaking point - Mum is sick and Ethan is taking the full force of his parents' deaths. In a terrible bargain, the Headmaster offers her a vision of his perfect world.
Realizing her mistake, Lizzie must rally the gang to take down the Headmaster once and for all - before he takes control of the Prime Minister, who is visiting Hazelbrook.
