Eccentric lottery winner, Charles, dreams of getting his favorite musicians, Mortimer-McGwyer, back together. His fantasy turns into reality when the bandmates and former lovers accept his invitation to play a private show at his home on Wallis Island.

As a happy-go-lucky pun enthusiast, comedian Tim Key slowly but surely melts the ice between two jaded musicians in this charming, offbeat comedy. Rekindling artistic passions and revisiting old wounds, Carey Mulligan and Tom Basden perform heartswelling folk songs with compelling chemistry to burn.
