4. The Driver

Josh and Sara piece together Austin’s final route into Damascus. They find the farm where he celebrated his 31st birthday - the last place his mother spoke to him.

Then comes an unprecedented discovery. For years, the story was that Austin was taken at a checkpoint. But what Josh and Sara uncover suggests something far more deliberate. And at the centre of Austin’s disappearance is one man.
