From the chilling classic novel by James Herbert, The Secret of Crickley Hall follows the story of Eve (Suanne Jones) and Gabe (Tom Ellis) Caleigh. A year after their little boy goes missing, the Caleighs come to Crickley Hall to try to escape the past and to get some space from the city where their little boy was abducted. It seems like the perfect destination until strange things start happening - cellar doors open of their own accord, hushed whimperings echo through the night and water seems to seep through impervious rock. But Eve Caleigh feels a connection with her lost son at the house and even thinks she sees him when she's there alone. It's almost as if something, or someone, in the house is trying to help her... Will they find their son before the evil that stalks Crickley Hall finds their other children?
