Episode 1

Journalist Adrian Chiles, former politician Edwina Currie, Olympian Fatima Whitbread, broadcaster Mim Shaikh, TV presenter Amar Latif, comedian Dom Joly and actress Pauline McLynn set out to cover sections of the Sultans Trail - a modern-day 2,200km pilgrimage across Eastern Europe that starts in Vienna and ends in Istanbul. Each has varying religions, with Dom and Pauline confirmed atheists. Starting in Serbia's capital Belgrade, they stay in basic hostels and sleep in shared dorms, acting as simple pilgrims traversing the ancient military route by rail and foot.
