Elvis Presley spends the summer of 1970 rehearsing and performing at the International Hotel in Las Vegas, and director Denis Sanders' cameras follow him from the sound stage to the stage lights. Backstage, Presley works through arrangements with his band, cracks jokes between takes, and argues good-naturedly with musicians over tempo and phrasing, footage that MGM's crew captured largely unscripted. Onstage, the film cuts together full performances, including "Mystery Train" and "Tiger Man," shot with multiple cameras to catch both the band and the audience reaction in real time. Interviews with fans lined up outside the hotel and with crew members preparing costumes and lighting fill out the picture of a production built around one man's return to live performance after years away from touring. There's no narrator shaping the story; the concert and rehearsal footage carries it. The film works as a record of a specific run of shows rather than a career overview, close enough to the stage to show sweat and missed notes alongside the hits.
