Poppy and Carise are frustrated. They're tired of watching the same old cycle: women in their office fall pregnant, leave early and take months off only to eventually return, requesting 'more flexibility'. All with smug smiles on their faces. That's why they create the 'No Baby Club' - a Facebook group dedicated to women like themselves who don't have children, who don't want children and who simply want to vent about the 'annoying mummies' in their lives. They create challenges designed to make sure that childless women reap the benefits, like leaving early for a fake appointment and making one of them pick up the slack for a change. Memberships soar. But as the group's tasks get more extreme, Carise starts to worry that they're taking things too far. On top of that, it seems that not all the new members are being honest and it's not long before things start to slide disastrously out of control . . .
