Reeling from a devastating loss, Tana (Lily Gladstone) is pulled back into the world by an unexpected invitation to her cousin’s wedding. After reconnecting with her Oglala Lakota family, Tana sets off to retrace a surreal journey that her grandmother took decades ago, searching for the spot captured in an old family photograph. A personal reverie summoned from a beguiling mix of fact and fiction, The Unknown Country is an arresting debut feature from Morrisa Maltz.
