A year after their little boy, Cam, goes missing, Gabe Caleigh takes his wife Eve and their two daughters to Crickley Hall to try and escape the past. It seems like the perfect destination - a big, rambling old house in the countryside and a chance for a fresh start. Then cellar doors start to open of their own accord, unseen children cry through the night and water seeps through impervious rock. At the centre of it all, a frenzied spectre wields a cane. Just as the Caleighs are ready to move out, Eve hears her missing son. Time shifts between present day and 1943 as the Caleighs desperately try to find out who the crying children are and what connects Crickley Hall to their son.
