Brand new period drama to sink your teeth into tonight starring Northern Irish actor Colin Morgan, who you'll know from the likes of Merlin, Humans and The Fall. Set in 1894, Morgan plays the role of Dr Nathan Appleby, who returns home to his family estate with his wife Charlotte following his mother's death. They soon realise that they need to turn the farm's fortunes around or risk ruin, and the devastation of the local community. However, when a young girl is brought to Nathan, seemingly possessed by a terrifying spirit, he cannot leave her to suffer, and uses every psychological technique he has to find a way to help her. He's convinced there's a rational explanation, but expect things to get a bit Conjuring at times.
