You can save hundreds of lives.
Or the one that matters most...

The atmosphere on board the inaugural non-stop flight from London to Sydney is electric. Numerous celebrities are rumoured to be among the passengers in business class and journalists will be waiting on the ground to greet the plane.

Mina is one of a hand-picked team of flight attendants chosen for the landmark journey. She's trying to focus on the task in hand, and not worry about her troubled five-year-old daughter back at home with her husband. Or the cataclysmic problems in her marriage.

But the plane has barely taken off when Mina receives a chilling note from an anonymous passenger, someone intent on ensuring the plane never reaches its destination. Someone who needs Mina's assistance and who knows exactly how to make her comply.

It's twenty hours to landing.
A lot can happen in twenty hours...
