We rented this movie last night from RedBox. I was really impressed with it. Amanda Seyfried does a great job of playing the role of the Jill Parrish.
Jill was kidnapped a year earlier out of her bed, taken to a national forest, dropped into a large hole and left there until her kidnapper decided he wanted to play with her. Amazingly she breaks away from the kidnapper and is found by hikers. A year later her sister disappears from their house. The character is paranoid and scared but determined to save her sister. She only has 12 hours and no help from the police to get this done.
It is a predicting plot but the way Amanda Seyfried portrays the panic driven character makes the movie. Watch this trailer below.
