In a cul-de-sac on the border between the sprawling suburbs and the country, Keith leads a solitary life where he keeps his offensive and compulsive tendencies to himself. He meets his young neighbour Grace while she is out looking for her missing dog, and an unlikely partnership follows. Grace wants to be a spy and Keith has the know-how. The trick is keeping your distance and watching - people aren’t always what they seem. Grace’s mother isn’t happy. It can only be sinister for this strange man to take an interest in her child. But there’s a secret threat closer to home, one that will drive Keith to take matters into his own hands - but only as a last resort.
