The blackout happened in seconds.

I was being transported to Adelaide when every engine on the highway died. Phones failed. Communications collapsed. Then I found five children stranded after a school bus crash.

Now I have to get them to Adelaide through a country falling apart.

But the blackout has unleashed more than chaos.

A dangerous man from my past is hunting the children.

I went to prison for killing a man.

Now I have five lives to save.
