The Queen's Free Chapel and College of St. George in her Castle at Windsor is famous as a "Royal Peculiar" under the sole authority of the Sovereign, yet it is less well known that the college has total responsibility for a quarter of the castle, and that with its clergy, lay staff, and choir, forms the largest community actually living within the castle walls. The choir is one of the best in Britain: they are seen rehearsing and performing a wide variety of superb music, from plainsong to contemporary work, as well as some much loved anthems and Christmas carols. This feature-length documentary traces St. George's remarkable story, from Edward III's founding vision in 1348 up to the present day. It also offers unique glimpses "behind the scenes" and of its more public and very special occasions: the magnificence of Garter Day, the tranquil beauty of choral Evensong, the joy of Easter, and the special magic of Christmas -- all in the unparalleled setting of St. George's Chapel.
