The Canal (2014)

Film archivist David (Rupert Evans) has had a rough time lately, suspecting that his wife Alice (Hannah Hoekstra) is cheating on him with Alex (Carl Shaaban), one of her work clients. This stress is compounded when David's work partner Claire (Antonia Campbell-Hughes) gives him a reel of to-be-archived footage that shows that his house was the setting for a brutal murder in 1902. David begins to believe that he has a spectral presence in his house; becoming progressively more unsettled and unhinged, he ends up following Alice to a nearby canal--and discovering that she is indeed having an affair with Alex. When she goes missing shortly afterward, David contacts the police, only to become the prime suspect in her disappearance. As the police grow more convinced that David has murdered his wife, he struggles to find proof of his growing suspicion that something otherworldly was responsible instead.—via Wikipedia
