During the time spent modifying her life after a troublesome past, Sarah and her young child, Chris, move to another Irish provincial home, nearby a woodland that shrouds an enormous cavity in the ground. A frightened experience with a puzzling neighbor pulverizes the effectively delicate conviction that all is good, throwing Sarah into a bad dream, loaded with suspicion and doubt. One night, Chris vanishes, yet when he returns he appears to be safe and unaltered. Be that as it may, his conduct turns out to be increasingly aggravating, making Sarah wonder if the kid who has returned is extremely her child. The lady endeavors to find if her child’s irritating changes are identified with the undermining depression profoundly covered up in the backwoods close to her home.
