Survival of the Fittest

When an experimental disease is accidentally released, a young girl has to face the trials of love, loss and survival while trying to save a band of guys. Astra isn't your typical teenage girl, she is a killing machine with a complicated past. Luke is the lead singer of 5 Seconds of Summer who has to over come his own morality of not killing. They both are fighting to keep their loved ones safe, but how are they going to keep each other safe?

Zombies lurk around every corner and with Astra having to teach Luke, Ashton, Michael and Calum everything she knows, she is in for a harder time than she thought. Will she rise to the challenge or fall at the first sign of danger?
