Iris.

A young couple embarks on a night in a remote forest in their van. When the young man briefly departs, their conversation in sign language reveals Iris to be deaf and mute. Once alone, Iris’ evening takes a sinister turn when she receives a series of ominous messages on her phone. These messages contain secretly taken photos of her in various locations, culminating in an image of the van at its current remote spot. It becomes clear that Iris is not alone. Fearing for her safety, she locks herself inside the van, draws the curtains shut, and turns off the lights, plunging herself into darkness and complete isolation.
