Fleeing from herself and the trappings of her previous life, Ann Thomas takes up residency at an outlandish crumbling hotel in the heartland of Wales as she awaits a life-changing operation. Illuminated by the distant glow of the Welsh firebombers, Ann's tenure at the hotel, which is full of secret passageways and inexplicable voids, pipes and sounds from the attic, entangles her life into that of its strange inhabitants; who include an outrageous con man and a grimly funny drunk. The hotel's insolent staff and a fanatic nationalist lure her further into a mysterious shadowland, where the hotel assumes a character of its own and a life riven with nefarious activities.
