It's the summer of 1967, and Paul McCartney's life seems to be perfect at this point. His band's just released a new album that's off the charts, and he's engaged to the girl of his dreams. Nothing could possibly make him happier than he already is, until he meets Linda Eastman.
Linda's so different than any other girl Paul's ever met, and he can't help but be drawn to her. They're only friends, but Paul knows his fiancée, Jane, wouldn't like it. Now he has to pick between keeping his already happy life- or ruining everything.
