National Geographic recently released a trailer of the limited series A Small Light, due to premiere this spring on Disney+.

The powerful, eight-episode production tells the remarkable story of a young secretary, Miep Gies (played by Bel Powley), who didn’t hesitate when her boss, Otto Frank (Liev Schreiber), asked her to hide him and his family from the Nazis during World War II. For the next two years, Miep, her husband Jan (Joe Cole) and several other everyday heroes watched over the eight Jews hiding in the back section, known as the “secret annex,” of Frank’s office building. It was Miep who found Anne’s diary and preserved it so that she and Frank could later share it with the world.

The series’ title comes from something Gies said late in her life: “I don’t like being called a hero because no one should ever think you have to be special to help others. Even an ordinary secretary or a housewife or a teenager can turn on a small light in a dark room.”

A Small Light is produced by ABC Signature in partnership with Keshet Studios for National Geographic. Executive producers and writers Joan Rater and Tony Phelan (ABC’s Grey’s Anatomy and Council of Dads) serve as showrunners, and Directors Guild of America award-winner and Emmy^®-nominated executive producer Susanna Fogel (The Flight Attendant and Cat Person) directs multiple episodes, including the pilot. Executive producers are Peter Traugott and Lisa Roos for Keshet Studios, Alon Shtruzman for Keshet International and Avi Nir for Keshet Media Group.
