A colleague of Michael Haneke, Jessica Hausner is a dark moviemaker. With surgically precise directing, she offers a solid sci-fi tale in which a mysterious plant releases a fragrance that makes people happy. Numbed, you don’t know if this is a story of human beings or body snatchers. Martin Gschlacht contributes his exceptional photography, and Teiji Ito (Maya Deren’s collaborator and husband), the awesome soundtrack.
