Nightworld

After he is forced to kill a teenager in self-defense, former LAPD police officer Brett Irlam retires to Bulgaria. There, he meets Ana and marries her. Her suicide sends him into a depression that worries his friend Alex, who suggests he take a security job in Sofia. Brett agrees when recurring nightmares of Ana's death keep him from moving on. The job turns out to be at a historic building well known by the locals. Its manager, Martin, reveals few details before hiring Brett. The job has only one major responsibility: watching CCTV footage of cameras in a locked warehouse. Martin explains that nobody has ever reported activity, but Brett must contact help immediately if he sees anything.
