I saw this for the first time recently.
A group of mountaineers go for a climbing and hiking trip in the Scottish Highlands. While taking a break for lunch, they discover a young girl buried alive in a small chamber in the wilderness....
Initially the film looked as if it will be similar to Deliverance, Southern Comfort, Vertige, Rituals aka Creeper, etc.
If it wud have stayed similar to the above mentioned films, then I wud have said been there done that so many times.
N now that the film is different from the above mentioned films, i wanted it to be similar to the ones mentioned above. At least it wud have done justice to the title.
