The feature-length documentary is shot through with archival footage including previously unseen home movies and clips from the famed August 1972 “One to One” benefit concert at Madison Square Garden, featuring John Lennon backed by guest musicians and collaborators alongside his and Yoko Ono’s Plastic Ono Band and backing band Elephant’s Memory.

The film features restored footage of the couple's only full-length concert together at Madison Square Garden in 1972.
