Giles and Monica arrive at Royal Mansour, one of the world's most discreet hotels, hidden deep in the heart of Marrakech's ancient Medina. In stark contrast to the developing country it inhabits, the 'jewel of the city' was built with a limitless budget by royal decree to showcase the kingdom to world leaders and to billionaire and celebrity guests.
Joanna ends her 5,000 mile journey in the place where she was born, Srinagar in Kashmir. She starts off in the Ranthambhore National Park, where she hopes to spot a tiger in the wild. Meeting tiger conservationist Belinda Wright, Joanna witnesses the work of local NGO Tiger Watch, who are attempting to break a cycle of poaching and poverty through education. Home to over 18 million people, Delhi is a city of stark contrasts. The extreme differences are obvious when Joanna visits a homeless community - where 10,000 men live under a flyover - and visits the modern part of the city where she has a go at working in a hi-tech call centre. The final leg of her journey takes her north from Delhi to Dharamsala, where she is granted a private audience with His Holiness the Dalai Lama. Joanna concludes her trip with a stay on a houseboat in Srinagar, as her parents did on honeymoon in 1941.
In this first episode, Simon travels to Burma to find out the roots of this crisis - as well as heading to Bangladesh to witness the drama that is still unfolding. He begins his journey in the biggest city in the country, Yangon, and drives north into Burma's Buddhist heartlands and the stunning ancient capital of Bagan - a sight that rivals the great wonders of the world. He meets the monks who supported the people through the darkest days of dictatorship. And he is granted an audience with some of the most contentious figures in the country - ultranationalist monks preaching hate against the country's Muslim Rohingya. Stopped from visiting the scene of the military crackdown against the Rohingya, Simon travels to Bangladesh to meet the refugees traumatised by the violence
