On a cold winter morning, a delivery truck backs into the loading dock of a popular shopping mall. Inside are eight boxes waiting to be picked up by Jodie, the store manager. But something's not quite right about the delivery. Jodie can sense it as soon as she touches the large, coffin-shaped something unnatural and dangerous is stored inside.

Almost as soon as the crates are brought into the store, things start to go wrong. Customers seem reluctant to linger. Clothes are thrown off the racks during the middle of the night. And Jodie's co-workers stop answering their phones.

As a deadly storm grows on the horizon, Jodie begins to realise just how dangerous the unknown can be.
