Businessman Lockhart (Dane DeHaan) is sent to a remote private hospital in Germany to retrieve the CEO of his company in New York. When he arrives he sees it's isolated in the mountains and learns it's built on the ruins of a castle that burned down two hundred years ago. The facility's director, Volmer (Jason Isaacs) is a bit strange and Lockhart has great difficulty talking to the CEO, who refuses to leave. He says he's sick and needs his treatment. This treatment involves drinking great quantities of the local water, which is purported to have healing properties. After a few days Lockhart decides to leave, empty handed, and is in a car accident when a deer runs into his car. He wakes up with a broken leg, and finds himself as a patient who they don't want to leave. He talks to other people there, who seem content, and comes across an odd girl, Hannah, who tells him that she's a special case. Is she related to Volmer?
As the movie progresses stranger and stranger things happen and Lockhart begins to piece together the horrific goings-on of this sinister place. And it is weird, the story picking up momentum and turning into something akin to a PHANTOM OF THE OPERA or FRANKENSTEIN film. A CURE FOR WELLNESS took me by surprise. Highly recommended.
