Driving home one night, a woman spots and old lady with a bag by the side of the road trying to hitch a ride. The woman has a strict rule about not picking up hitch hikers when she's alone, but can't help but feel sorry for the old woman and decides to make an exception, so she pulls over and picks up the old woman.
A few minutes into the ride, the woman can't help but notice that the old lady has oddly hair arms and immediately becomes paranoid.
The woman immediately pulls over, concocting a story about a problem with the car, and asks the old lady to get out and check the tail lights. The old woman complies and climbs out of the car.
As soon as the old lady is out of the car, the woman locks the doors and drives away.
Some time passes and the woman has time to calm down. It's then that she begins to regret her actions. What if she was wrong? What if the woman really was just an innocent old lady who needed help, and she'd left her alone by the side of the road.
It's then that the woman notices the bag the old woman was carrying sitting in the passenger side footwell, having been left when the lady climbed out of the car to check the tail lights.
The woman pulls over, grabs the bag and peers inside. A gasp escapes her lips as she lays eyes on the contents:
Rope, duct tape and a freshly sharpened kitchen knife.
