New York City newlyweds Jude (Girls’ Adam Driver) and Mina (I Am Love’s Alba Rohrwacher) have a seemingly perfect relationship. But things take an unsettling turn with the birth of their son. Convinced that the baby must be kept free of all contaminants, Mina develops fanatical obsessions with veganism, cleanliness, and purity that may kill the child unless Jude can stop her. With stunning performances from Driver and Rohrwacher, this intense psychological drama suggests that sometimes a parent’s love can be the scariest thing of all.
