The musical follows the relationships of what at first seems like two different couples separated by a span of time; one couple is getting married and the other is getting divorced. It turns out they are actually the same couple at two points in their relationship-a decade apart.
Director Nick Winston said: "Tomorrow Morning is the story of one couple seen in two separate timelines, a decade apart. This is a story of life, love, misunderstanding and hope... a universal and timeless tale"
