Lizzie, Megan and Sam became accidental friends over good coffee, banter and wrong-world jokes at school drop off. Lizzie is a part-time midwife with four kids and a secret past. Sam is an ex-chef and stay-at-home dad with an absent, high-flying corporate wife. Megan is an ex-model single mum with a thriving online business and no time for loneliness. None of them are very interested in the world of school concerts and working bees until the day the lollipop man dies and ruins everything.
