Story 1: Government Building Intruder [0:21]

A security guard with six years of experience takes on weekend overnight shifts at a new, remote government building contract to earn extra money. The building is located far from civilization, surrounded by woods and a high fence with barbed wire. One Saturday night during a severe thunderstorm, the guard sees a figure moving outside the fence. Soon after, a camera overlooking the back parking lot is knocked out. Then, an access point alarm goes off, indicating someone has entered the building using a code. The guard's phone and the office phone are out of service, and the power is cut. Armed but hesitant to shoot, the guard attempts to escape, leading to a tense chase through the dark stairwell. The guard creates a diversion and eventually escapes to his truck, pursued by a masked figure in black. After calling the police, a search of the building reveals a dropped, unregistered handgun. The motive for the break-in remains unknown.

Story 2: Corporate Office Building Stalker [11:01]

A security guard working the night shift at a corporate office building in New Jersey notices a figure moving between cars in the underground parking garage, which should be empty. The person is wearing a long, dark coat and doesn't appear to be heading anywhere specific. After alerting his supervisor, the guard checks the garage in person but finds no one. Upon returning to the security monitors, the figure is back in the same spot. The guard watches the figure move toward the stairwell and disappear. Wet, bare footprints are then discovered leading from the elevator into the main lobby. While patrolling the fifth floor, the guard finds an office door ajar and hears heavy, wet footsteps behind him. He flees to the stairwell, barely escaping. When backup arrives, the building is searched, but no one is found, and the camera footage is corrupted. The guard quits his job a month later, haunted by the feeling of being stalked.

Story 3: Medical Clinic Break-in [18:34]

A mobile security guard on his first night of training accompanies his supervisor to a medical clinic in Missaga for a routine perimeter patrol. They discover the underground parking garage open and the front door broken. The elevator is moving between floors, indicating someone is inside. The guards enter cautiously and take the elevator to the top floor, finding it dark and empty. They hear footsteps in the stairwell and call for backup, suspecting an ambush. After a tense 15-minute wait, a senior supervisor arrives, and they search the building but find no one. As they are searching the third floor, they hear the front door open and someone running outside, but they are unable to catch the suspect. The guard is left shaken by the experience, unsure whether the clinic was broken into or haunted.
