A vanished wife. A crumbling marriage. And a web of explosive secrets.

Pregnant and living an Insta-perfect lifestyle, Sarah seems to have it all. But one evening halfway through making dinner, she vanishes into thin air leaving behind her keys, her handbag and James, her bewildered husband.

The pans are boiling over and the smoke alarm is screaming, but he is alone in the house.

Keen to get their picture-perfect life back on track before their followers start wondering where his wife is, James desperately tries to find her.

But her sister Kate is the only one who knows Sarah has run like this before. And she's terrified for her sibling and for the unborn child she is carrying.
