The group of friends consists of five young adults, who are all excited to embark on a weekend getaway to a mountain retreat. They rent a cabin in a remote location, looking forward to hiking, exploring, and enjoying each other's company.
One evening, as they are sitting around a campfire, they hear strange noises coming from a nearby cabin. Curiosity gets the best of them, and they decide to investigate. What they find is a horrific scene of a violent murder - a man brutally killed and left for dead.
Shaken and traumatized, the friends decide to cut their trip short and head back home. However, the killer has other plans and follows them back to their city.
As the friends try to move on from the terrifying experience, they start to notice strange things happening around them. They receive anonymous phone calls, hear unexplained noises in their homes, and see glimpses of the killer lurking in the shadows.
The group becomes increasingly paranoid and mistrustful of each other, as they try to figure out who the killer is and how to protect themselves from him. As the tension builds, secrets are revealed, and the friends realize that they are not as safe as they thought.
In a race against time, the friends must band together and fight back against the killer before he claims his next victim.
