The film centres around a young Balkan girl (played by Rosie Day) forced to work in a rape house during an unspecified war, who kills a militiaman and goes on the run.

The film is being produced by Michael Riley of London-based Sterling Pictures. Riley has two other films due for release, JK Amalou’s Deviation (for which he served as co-producer, to be released by Revolver) and underworld comedy Hard Boiled Sweets, which Universal is releasing in the UK.

Sterling is hoping to go into production on three projects in 2012, psychological thriller The Black Site, Jasmin Dizdar’s The Gadfly and Chee Keong Chung’s futuristic MMA horror Zombie Apocalypse).
