Enter Nowhere (2011)

Jody and her boyfriend Kevin rob a convenience store in a gas station and Jody orders the attendant to open the safe, while Kevin asks her to go away. Meanwhile, the pregnant Samantha "Sam" walks in the woods and stumbles upon a remote cabin. She meets Tom and tells him that her car ran out of gas and her husband walked on the road looking for help and never returns. He tells her that he had a car accident four days ago and did not find any help. They stay in the cabin since the place is too cold in the night reaching -5 degrees Celsius. On the next morning, they bring blankets from Sam's car and out of the blue, Jody appears on the porch of the cabin. She is aggressive and rude in the beginning, but soon they team-up trying to find a way out of the place they are, but they always return to the cabin. The mystery increases when they discuss in which state they are. When Sam sees the bills stolen by Jody, she believes it is a joke since they are printed in 1984. Soon they learn that Sam is from 1962; Jody is from 1985; and Tom is from 2011. What has happened to them?
