Using new and exclusive interviews, 'Beaties' Biggest Secrets' reveals the inside story of the world's greatest-ever pop group, carrying explosive revelations about the extraordinary lives of Liverpool's favourite sons. The film begins with Lennon's death in 1980 but then tracks back to the early 1960's at the time of the group's formation and their early days in Liverpool. The story then travels forward through their careers from learning their craft in dingy strip joints to global domination as the world's greatest ever pop icons. This is the Beatles at their best - and their worst. This is the first fully rounded portrait to appear on video.
