The first trailer for upcoming psychological horror flick Citadel has been released.

Directed by Ciarán Foy, Citadel follows the life of Tommy Cowley (Aneurin Barnard), who lives in a decaying apartment with his pregnant wife. The couple are attacked one day by a group gang, who kill Tommy’s wife, leaving him to raise his newborn daughter alone.

So shaken by the events that he’s developed extreme agoraphobia, Tommy alternates days hiding out indoors in his new flat from imagined threats and intense therapy sessions aimed at bringing him back to normalcy.

However, when the same gang, seemingly intent on kidnapping his daughter, begins terrorizing his life again, he’s torn between his paralyzing fear and protective parental instinct. With the help of a vigilante priest who has uncovered the origin of this ruthless, potentially supernatural gang, Tommy must overcome his fears and venture into the heart of the abandoned tower block known as the Citadel to save his family.

The film received rave reviews after being screened at Austin’s SXSW Film Festival. It also won the Midnighter Audience Award at the festival for ‘bringing a fresh take to classic horror’.

Citadel is due for an October 26 release, just in time for Halloween.
