The family man David (Rupert Evans) and his pregnant wife Alice (Hannah Hoekstra) buy an old house nearby a canal to raise a family of their own. Five years later, their son Billy is the pride and joy of the family. David works archiving and editing films for his partner and friend Claire (Antonia Campbell-Hughes). When she gives a reel of a 1902 footage to work, David learns that his house was the place of a violent murder. This discover haunts David that sees a stranger inside his house threatening his son. When he finds that Alice is cheating on him with her client Alex (Carl Shaaban), David sees the stranger killing Alice and becomes obsessed to find who the suspect might be. Meanwhile he becomes the prime suspect of the police with his disturbed attitudes.
"The Canal" is an ambiguous horror movie with the story of a man that has a breakdown after learning that his home was the place of a brutal murder in 1902 and that his beloved wife is cheating on him. The story of haunting, obsession and madness has a confused screenplay and slow pace. But the acting and the dark cinematography make worthwhile watching this movie with low expectation and have a surprise. The creepy conclusion is the ambiguity of the story. Was David really insane? My vote is six.
Title (Brazil): "O Canal" ("The Canal")
