When schoolteacher Ben unearths an old door knocker in the garden of his new home, the curator suggests it may come from the now-demolished house, reputed to be haunted. Ben prompts the curator to tell him stories about the house's past: a corrupt Georgian businessman finds something unexpected in the woodwork of his new home, while a 1920s young couple's happy engagement party is spoiled by the spectre of a ghostly bride. Back in the present, Ben finds himself in dark and dangerous waters.
