Herb McGwyer (Tom Basden), turns up in a rickety boat to Wallis Island expecting an intimate, rural festival-type gig. Only, his hotel is actually the home of Charles (Tim Key); the audience is, well, Charles; and, unbeknownst to him, he’ll be reuniting for the first time in a decade or so with his ex-musical and romantic partner, Nell Mortimer (Carey Mulligan).

The Ballad of Wallis Island is an affecting comedy that contemplates the pains and pleasures of a musical career in freefall.
