A man journeys by rail to a nameless sanatorium where his father has recently died. Once there, time loses its linearity and he finds himself in a world that appears both strange and strangely familiar.
Unfortunately the movie Sanatorium Under the Sign of the Hourglass is not yet available on HBO Max.
