Austria, late 19th century. Countess Irma Sztáray (Sandra Hüller) leaves her home in Hungary to become the lady-in-waiting for Empress Elisabeth of Austria (Susanne Wolff), known to those close to her as Sisi. Irma falls under the spell of the rebellious Empress Sisi, and the two form a strong bond during a summer retreat in Greece. However, once home in Vienna, their lives take dramatic and irrevocable turns. "Lush, irreverent" (Variety) and "vividly shot" (Alliance of Women Film Journalists), SISI & I features Academy Award-nominated Sandra Hüller and Susanne Wolff in a "thought-provoking and entertaining glance at the famous empress" (Cineuropa).
