Citadel

Tommy Cowley (Aneurin Barnard) lives a quiet life in a decaying apartment complex with his very pregnant wife. The couple is attacked one day by a group of hooded young thugs, and after a shocking act of violence, Tommy is left to raise his newborn daughter alone. So shaken by the events that he's developed extreme agoraphobia, Tommy alternates his days hiding out from imagined threats in his new flat and intense therapy sessions aimed at bringing him back to normalcy.
