When Eddie finds out he has an identical twin brother, Jasper, he sees an opportunity to escape his seedy life of petty crime. He decides to steal Jasper's life. But as Eddie begins to fall in love with Jasper's wife, Caitlin, he discovers a side of himself he never knew existed.

A dark thriller in two parts that reflect each other: The first tells Jasper's story. The second tells Eddie's.

Demon Brother is a story about identity, sex and death. Shaun Dingwall (New Tricks, Young Victoria, Doctor Who) stars opposite himself as the two brothers, Jasper and Eddie - one good and one very bad. Valene Kane (The Fall) makes her radio debut as Jasper's wife Caitlin. With supporting performances from Vera Filatova (Peep Show) and Kenneth Cranham (Made in Dagenham, Layer Cake, Shine on Harvey Moon).
