It is the story of a young and ambitious worker of a New York company who is given an important mission to visit a forsaken health center in Swiss Alps in order to get his boss back out of the prolonged vacation. He warned everyone that he is not going to be back by means of a strange letter. It makes it to where everyone worries in the company and which is why a man was sent there to solve this problem. There are rich and powerful people having a rest, stressed due to hectic life for a treatment with a water with curative powers.
On arriving and spending some time within its walls, he realizes that miracle-working procedures of spa-saloon are not what they seem to be. While the main character begins to unwrap scary secrets of the place, his sound mind undergoes a checkout for stiffness. Despite all the attempts, Lockhart is not allowed to meet his boss due to some reasons.
Failed to accomplish the mission, he is going to go back to New York but it looks like now he suffers from the same weird illness, which is the reason why all the rest guests of the center are there wishing to get their dose of the cure. With each new day, hopes of Lockhart to be cured and returned home are fading away. Instead, he has thrilling hallucinations and borderland between fact and fiction disappears.
Will Lockhart be able to work it out and overcome the longest of odds to leave a doubtful resort, which has become a real jail for him and other patients?
Overall, I liked the movie even though it is rather difficult to watch it on a psychological level. As long as I am writing about it, I would highly recommend it for watching. To whom? To people over 18 who love psychological thrillers.
