Ever since Paul's wife-to-be abandoned him at the altar, he's given up all hope of ever falling in love, and while it hurts to see the other members of his band happily married, he's firm with his decision.
In 1967, just after this takes place, the Beatles are dealing with the stress of the loss of their manager and the planning of their upcoming tour and album. The press has been attacking Paul with the rumors of his failed wedding and he's about ready to break down. The next person to try and take his photo, however, is Carmen Dalton, an aspiring photographer who spots him outside of Abbey Road studios one day and attempts to take his picture, an action to which Paul responds by breaking her camera.
When his secretary makes him take her out to lunch as an apology, though, he finds that he actually has a lot in common with Carmen and rather likes her. So what'll she do when he invites her to accompany him on the Magical Mystery Tour? And what'll he do if she falls for him?
