After their school excursion goes wrong, Jake, Felix, Andy and Sam spend the night in the bush, sheltering from a crazy storm. When they finally stumble home, they discover something as weird as it is scary: no-one knows them.
Not their parents. Not their brothers and sisters. No-one.
The more they try to figure out what happened, the stranger things get. Only one thing is clear: this world knows they don't belong here, and it wants them gone...
