One-time talented golfer, Wallace Avery (Colin Firth) is struggling with a life from which he longs to escape. Faking his own death, he acquires a forged passport and a new identity — that of a golfer named “Arthur Newman”. “Arthur” heads out for Indiana to start a new life and a promise of a new job as a resident golf pro at a prestigious club. Along the way, he meets the beautiful but troubled "Mike" (Emily Blunt), who is also travelling under a false identity — that of her schizophrenic twin sister. Arthur and Mike’s relationship flourishes and they embark on an adventurous road trip where they take a deviation, break into empty mansions and assume other people’s identities until, eventually, the role-playing games begin to lose their lustre, revealing two hearts hurt by life’s challenges. Arthur & Mike are then forced to take another look at themselves and the real lives they’ve left behind.
