Knifepoint

Jill took a job which sounded perfect for the summer, guiding tourists on trail rides in the beautiful mountains. She didn't realize that the money was terrible, the hours long and the coworkers insufferable. After a blow-up with her boss, she takes a single man into the mountains for a ride, only to find that he is a dangerous killer. When Jill fights back and manages to escape, she is in a desperate race to survive and make it to safety.
