Really, really enjoyed this - excellent low-fi production that makes an asset out of its budgetary constraints. This is a taut thriller that grips throughout, maintaining the tension and then sticking the landing via a series of third act twists. Solid cast - particularly Mirren Mack (from the excellent Sex Education) as Carla, who is very convincing in a complex part - and good pacing kept me intrigued, invested and guessing throughout. Really enjoyed the score and clever use of handheld and security camera footage to build atmosphere - the intensity was maintained throughout. Highly recommended.
