What if you only had 3 minutes to save your own life and the clock is already counting down...Three minutes. Nessa, Megan and Anto know that any day now they wake up alone in a horrible land and realise they've been Called. Two minutes. Like all teenagers they know that they'll be hunted down and despite all their training only 1 in 10 will survive. One minute. And Nessa can't run, her polio twisted legs mean she'll never survive her Call will she? Time's up.
