I'm Gonna Shoot Your Head Off

The assistant manager of a sporting goods store calls 911 as one of her customers uses an electric saw to cut his way into the store's ammunition and gun rack. While on a family hike, two mothers call 911 seconds after witnessing an ice cave crash down on their two teenage sons. And when a young receptionist starts her day shift at LA Tan, she never imagines that she and another customer will come face-to-face with a serial killer in training.
