The play is based on a thriller of the same name in an affluent suburb of Sydney where two women happen to be in a supermarket. They are all of the same age, pregnant and giving birth at the same time. Agatha works as a shelf stacker in a supermarket, while Meghan is a rising "mommy blog". Although they live in roughly the same part of the city, they come from different worlds-they live on very different trajectories. Agatha lives in a poor apartment building, has few real friends, and lives in a poor apartment. She emigrated from England to Katoomba (on the outskirts of Sydney) with her family at the age of 14, but had no real contact with the mother of Jehovah's witnesses who still lived there. Agatha's baby Hayden, who had a brief relationship with her, was the father of a sailor who served in HMAS Sutherland. He forgot that there was a child on the road. Meghan is an upper middle class. Her husband, Jack, an ambitious television sports journalist, is often recognized in bars. Let's meet first.
