Stay Close tells the story of three people hiding dark secrets and living lives they never wanted. Megan is a soccer mum with a wild past and growing sense of dissatisfaction; Ray's talents as a documentary photographer are being wasted in a dead-end paparazzi job; while Broome is a detective struggling to let go of a cold case. Eventually, the consequences of their past actions crash together in the present day.
On the surface Kitty, Margot, Bree and Olivia appear to have nothing in common - but there's one passion which unites them: to expose injustice. They form their own secret society, DGM - they Don't Get Mad, they Get Even - playing anonymous pranks to expose bullies.
