The Road to Palmyra follows historian Dan Cruickshank and legendary photographer Don McCullin into the heart of war torn Syria, on a dangerous mission to document the cultural destruction wrought by Isis, and to understand what it means to the people of the nation. Their final destination is the ancient city of Palmyra to find out what remains of the ruins after Isis fled. These stones represent the very soul of Syria, and the debate about what to do with them is about to begin. For both men, it is a return journey to a place with which they have long been obsessed. But to get there, they have to travel through a country still in the grip of war.
