Joel (Leigh Gathercole), a bitter, isolated blind man is reunited with his sister, Maggie (Lee McClenaghan), for the first time in six years. A cold distance is felt between the two siblings - Maggie is a successful, confident doctor; Joel is stricken with self-pity and jealousy after his accident. When a great secret is revealed, a psychological battle begins between the two, turning Joel’s warped reality on its head. It’s up to Joel to gather his bearings, ensure his safety, and either mitigate - or split forever - his relationship with Maggie. Told from Joel’s perspective, making the viewer only ever privy to what he is aware of, Double Blind is a tense, claustrophobic, fresh thriller.
