De film brengt het verhaal in kaart van een excentrieke loterijwinnaar, Charles, die alleen op een afgelegen eiland woont, maar probeert zijn dromen waar te maken door zijn favoriete muzikant, Herb McGwyer, in te huren voor een exclusief privé-optreden. Zonder dat Herb het wist, heeft Charles ook Herbs ex-bandmaat en ex-vriendin Nell ingehuurd, samen met haar nieuwe echtgenoot, om de oude favorieten uit te voeren. Terwijl de gemoederen oplaaien en oude spanningen weer de kop opsteken, houdt het stormachtige weer hen allemaal gevangen op het eiland en Charles zoekt wanhopig naar een manier om zijn droomoptreden te redden.
Nee, helaas is The Ballad of Wallis Island nog niet beschikbaar op Netflix in Nederland.
