In this low-key sci-fi drama, Martina Gedeck plays a woman who travels to a secluded cabin in the mountainous Austrian countryside; one morning she finds that an invisible wall surrounds the valley on all sides, and after numerous attempts to escape she resolves to lead a life of solitude. Based on the 1963 novel by Marlen Haushofer, a sort of transcendental character study, the film is an elegant, slow-burning exercise in narrative minimalism; director Julien Pölsler never fully explains the origins or purpose of the wall, favoring mood over logic. In German with subtitles.
