In 1986, in Scotland, Angela and Jackson are two American siblings who, with a small team of paranormal investigators, run a fake medium scam on clients who believe their houses are haunted. The team utilizes such things as recordings and trip wires to convince clients they've caught evidence of spirits, and uses the reputation of the siblings' late mother to promote Angela's powers as a medium. Meanwhile, Jackson is revealed to have been orchestrating the scams because of a debt he owns to loan sharks.
