The story of two remarkable weeks in 1964, when Beatlemania first ignited in America. From airport to hotel to TV studio, the pioneering Maysles brothers were at the Beatles' shoulders on their first US visit. The siblings filmed them off guard and off duty, in nightclubs, at photo shoots, press conferences, in limos and on trains. The footage includes a performance on the Ed Sullivan Show, when they played to 73 million television viewers, and their concert at the Washington Coliseum.
