Film Synopsis | Eccentric millionaire Charles (Tim Key) dreams of reuniting his favourite folk-rock duo, McGwyer and Mortimer, so he invites the estranged bandmates and former lovers, Herb McGwyer (Tom Basden) and Nell Mortimer (Carey Mulligan), unbeknownst to each other, to perform a private concert at his home on the remote (and fictional) Wallis Island. Problems arise, needless to say, the most immediate being Nell has arrived with her husband Michael (Akemnji Ndifornyen); the old musical magic might still be there, but so are the issues that broke the duo apart.
