This documentary film set in 1972 New York explores John and Yoko's musical, personal, artistic, social, and political world set against the backdrop of a turbulent era in American history. At the core of the film is the One to One Charity Concert for special-needs children, John Lennon's only full-length concert between the final Beatles concert in 1966 and his death. The film includes a wealth of previously-unseen Lennon archives including personal phone calls, home movies filmed by John and Yoko, and restored and remastered footage from the One to One concert with remixed audio overseen by Sean Ono Lennon.
