Who is Laura Clark?

To her colleagues at the suburban head office where she works, she's an anonymous forty-something HR manager who spends her days sending emails about the maintenance of the lifts, organising snacks for work meetings and subtly managing everyone's egos so things can actually get done. To her golf-obsessed husband and selfie-obsessed teenage daughter, she's the woman who puts dinner on the table and cleans it up afterwards. To her elderly mother, she's a sounding board for her constant complaints.

But one day Laura puts on her 'out of office' message and doesn't turn up for work. Soon baffling things start happening, and everyone's formerly ordered lives quickly begin to descend into all-out chaos.

Where has Laura gone? Has something terrible happened to her? Or has she - unthinkably - decided to finally give her own life the finger?

To find out, the people in her life must realise that, maybe, they never really knew Laura Clark at all . . .
