John and Kyra, two friends who escaped London for the peace and quiet of the small coastal town of Whitby in the north of England, find themselves staying in the town as lockdown begins. With a virus sweeping across the world, growing ever more virulent and dangerous, the two friends decide to ride out the lockdown with good food, plenty of booze and their own company.

It soon becomes clear that the people who die, don't stay dead. While the government and emergency services fail to contain the threat the two friends find themselves a long way from home as the world collapses around them. With survival paramount, they have to do what ever is needed, no matter the cost.

This is how it ends.
