Saul Dibb's low-budget feature exposes the increasing danger posed by British gun culture as seen through the eyes of young men for whom violence has become a way of life.

Having served his time behind bars, 20-year-old Ricky (Ashley Walters) returns home to live with his mother (Claire Perkins) and 12-year-old brother Curtis (Luke Fraser). The jailbird is keen to impress on his loved ones that he is going straight; on this basis, he tries to win back his ex-girlfriend.

However, when Ricky's best friend Wisdom (Leon Black) incites a feud with a local thug, the former inmate finds himself being drawn back into his perilous old life.
