Emily (Rooney Mara - The Girl with the Dragon Tattoo) and Martin (Channing Tatum - The Vow) are successful New York couple whose world unravels when a new drug prescribed by Emily's psychiatrist (Jude Law - Sherlock Holmes) intended to treat anxiety has unexpected and dangerous side effects. From director Steve Soderbergh (Contagion, Magic Mike, Ocean s Eleven, Twelve, Thirteen) comes a riveting psychological thriller where neither the symptoms nor the cure are quite as straightforward as they seem.
