Mishal Husain joins Oswin and Carla for a truly special Season 4 opener, telling the tale of her family's journey through the stormy waters of Indian and Pakistani independence. It's a story of joy and freedom, but also one of fear, loss and terror.

Shahid, Tahirah, Mumtaz and Mary live through Empire, world war, independence and partition. They meet the people who will shape their future, men like Mountbatten and Jinnah - but they also find themselves unable to meet the people who really matter to them, the friends and family they grew up with but who end up on the other side of an embattled border.

It is a truly powerful episode, reminding us that we all have 'history' big and small within our grasp, within our family.
