Two women have a chance encounter in a supermarket in an affluent Sydney suburb. They are the same age, both heavily pregnant and due at the same time. Meghan (Jessica De Gouw) is a glamorous online influencer on the rise with an ambitious television sports reporter husband Jack (Michael Dorman). Agatha (Laura Carmichael) is a loner, barely subsisting above the poverty line. Both women have secrets. And both will risk everything to conceal the truth. But their worlds are about to collide in one shocking act that cannot be undone.
