Julian suddenly grabs Abby and struggles with her for a few moments as she tries to reach her gun. As some suspenseful music plays at night, we see that someone's working on a locked door at Ray's place. As a vehicle approaches, that man scrambles to get the wounded person out of sight. That victim then holds a gun on the man with the shovel and slowly pulls the trigger several times, but the gun's empty. A person shows up at an office where the killer is hiding nearby.
Blood then spills out of a person's mouth in what turns out to be a nightmare.
We see the scope point of view of someone aiming a gun at other people in an adjacent building. One person is then shot and the other scrambles for cover, trying to break the light bulb that's illuminating the room at night. In the dark, that person then hears the sounds of someone approaching and working at the lock on the door. A person slams a window down onto another person's hand and then stabs a knife through it, impaling the hand to the windowsill. From that point on, as that first person tries to elude the second, some tense and suspenseful moments follow.
