The story revolves around William Shawcross and Mary Gilcrest, along with William's two daughters Kate and Julia, Mary's two sons Brendan and Terence, William’s business associates Arnold and Jane, his housekeeper Mrs Ball, his bandleader Billy Two Hats, his cousin and solicitor Nicholas, Mary’s mother Molly, her ex husband Reuben, her ex boyfriend Rick, and her midwife associate Doris. William is an undertaker and Mary a midwife; according to Mary, they “complete the circle … I see them into the world and you see them out”. Subplots regularly involve their work with clients. William is also an avid musician, singing in a choir and playing in a band, and music figures prominently in the story and the production.
