When Laura returns from maternity leave to work in a marketing agency, something isn't right.

Mia was only supposed to be temporary cover for Laura, but now she's staying permanently. Struggling with the burdens of work and motherhood, Laura starts to feel her life is slipping away.

Then comes the fire - gutting the agency's offices - and the body pulled out of the wreckage.

The police want to talk to three women.

There's Janie, utterly devoted wife to the CEO.
There's Mia, the agency's bright new talent.
And there's Laura, a loyal employee of many years.
