Sarah Roberts boards a plane in Toronto to Amsterdam. Sarah knows the plane will crash during the flight. She's powerless to keep the flight from taking off and powerless to prevent the crash. But per her sister Vivian, she boards anyway. Through the course of the flight she meets Casper, a stranger who has been watching her. He often disappears throughout the flight, but not before revealing he's carrying a gun and a knife.
With Vivian's help, Sarah survives the crash and her actions save nearly a hundred people.
The Netherlands authorities arrest Sarah as witnesses on board claim she knew about the crash beforehand. The Netherlands police, a division of the Ministry of Defense, don't appreciate Sarah Roberts in their country and decide to bring her up on terrorism charges unless she complies with an undercover sting operation underway that day. During the eight-hour flight and subsequent incarceration, Sarah tries to get a message out to her boyfriend Aaron back in Toronto about someone following him. Someone extremely dangerous. But the message doesn't get through.
Sarah's after a black book held by a mysterious Chinese man. He has links to a trafficking ring that forces women to work in Torture Clubs in Amsterdam, Athens, and Moscow. This black book filled with names, dates and incriminating evidence could put a lot of people behind bars. This book will also free up hundreds, if not thousands of girls being trafficked around the globe. These girls are The Abandoned ones and Sarah is determined to locate the book and liberate them. But what she doesn't realize is that in the process, she has abandoned the people who need her the most. While she traipses around the world, Aaron is drugged, bound and gagged and taken on a days' long journey to a remote, makeshift prison near Tijuana, Mexico, where his life will be changed forever. Sarah has more than she can handle in The Abandoned, and Vivian is afraid for her in ways she won't speak of, knowing it would be too much for Sarah to handle. Just doing her best won't be good enough anymore.
