A quiet town is hit by a supernatural event, leaving everyone unconscious and changing the area's fate forever.

As Midwich recovers from the devastating effects of the blackout, a truly horrifying discovery is made and a town meeting is called.

Three years after the blackout, Midwich's placid state is interrupted by the arrival of a new child.

Desperate to understand the source of the children's violent instincts, Susannah takes a risky step.

With Susannah ostracised, the children's hold on Midwich strengthens. When Paul awakens to the children's true nature, he pleads with Susannah to try to forge a truce with them. Meanwhile Zoe and Sam are galvanised into action by another miracle.

Two years later. The children go behind Susannah's back to express their desire to leave Midwich and Susannah suspects ulterior motives at work. Meanwhile, tragedy strikes one of the families. Paul and Susannah work together to uncover the truth.
