The brewery have called “time” and it’s the last night at The House of the Dead — the most haunted pub in Wales. Barry the barman has invited renowned psychic, Mrs Wintergreen, to hold a special seance to mark the occasion, and there’s a big crowd hoping for the chance of seeing their deceased loved ones for one last time. But when Jack arrives on the scene, he’s determined to stop them. Ianto is puzzled by Jack’s behaviour, and Gwen is suspicious. Why is Jack acting so strangely? Then the ghosts start arriving — and all hell breaks loose.
