In the comments is the trailer for Derek Mungor’s POV slasher You Are Not Alone. While the footage itself isn’t all that exciting, the trailer itself is shockingly effective.
In it, “As seen from the first-person POV, Natalie, a recent college graduate, reconnects with friends and family as she visits her hometown over the Fourth of July. The town is inundated with news of a dangerous sociopath who is in the midst of a spree killing and reportedly within the area. Experience what happens when Natalie crosses paths with said killer.”
