Christmas shopping can be murder.

It’s Christmas Eve at the Emporium, a bespoke gift shop hidden in the depths of London’s winding streets, where a select few shoppers are browsing its handcrafted delights.

But when they go to leave, they find the doors are locked and it isn’t long before they realise this is no innocent mix-up. The shoppers have been trapped here by someone who knows their darkest secrets, who will stop at nothing until they have all been unwrapped – and there is a gruesome gift waiting in Santa’s grotto . . .

For those that survive the night, it will be a Christmas to remember.
