A doctor, called Luke, gathers stories and details about a man who had turned his world upside down - a man who changed his life and whose life had changed history. He then writes them all down in a letter to send to his friend Theo. This is an epic journey with Jesus, the Son of God, and his first followers. It's the story at the heart of the world's best-selling book - a book that's been burned or banned by different authorities over 20 centuries. It's a story that has thrived and survived, transforming lives even in parts of the world where it's forbidden.
