Set in an uncanny future — or perhaps a slightly alternate present where cellphone technology is nowhere to be found — Anna and her partner Ryan have achieved every couple’s dream: they are in possession of a document certifying their true love. Their comfortable if somewhat mundane life, however, leaves Anna questioning their successful love test, administered by placing their extracted fingernails into a cutting-edge machine. Anna soon begins working for the Love Institute under the tutelage of Duncan (Luke Wilson), which, in addition to determining a couples’ status via the mysterious test, trains them to deepen bonds. There, she’s paired with the experienced — and devastatingly charming — Amir to take couples at various stages of relationships through a series of love-building activities before the big test. As the new colleagues work to ameliorate the connections of clients, Anna begins to wonder if perhaps Amir is her one true love and if trusting her own feelings is a more reliable metric than what is determined by a machine.
