John (Ed Speleers) and Karen (Zoë Tapper) are stuck in a loveless marriage. After they discovered that Karen was infertile, and their last child stillborn, they haven’t stayed together out of love but complacency. Mindlessly shuffling their way through life, propped up on copious amounts of drugs and alcohol to be even remotely interested in this existence, all while they both stay on the cusp of a divorce but ultimately unable to take that plunge. You can see why, once the zombie apocalypse breaks out across the world, their lives haven’t really changed that much.
