Yesterday, everyone knew The Beatles. Today, only Jack remembers their songs. He’s about to become a very big deal.
Jack Malik (Himesh Patel, TV's 'EastEnders') is a struggling singer-songwriter in a tiny English seaside town whose dreams of fame are rapidly fading, despite the fierce devotion and support of his childhood best friend, Ellie (Lily James, 'Mamma Mia! Here We Go Again'). Then, after a freak bus accident during a mysterious global blackout, Jack wakes up to discover that The Beatles have never existed... and he finds himself with a very complicated problem indeed.
Performing songs by the greatest band in history to a world that has never heard them, and with a little help from his steel-hearted American agent, Debra (Emmy Award winner Kate McKinnon, TV’s 'Saturday Night Live'), and his kind-but-wildly-unreliable roadie Rocky (Joel Fry, TV's 'Game of Thrones'), Jack’s fame explodes. But as his star rises, he risks losing Ellie - the one person who always believed in him. With the door between his old and new life closing, Jack will need to get back to where he once belonged and prove that all you need is love.
