Conversations without borders

We join a group of American tourists on an organised trip across the border to find out what life there is really like. Also, a trilingual interpreter tells us about the challenges of interpreting for asylum seekers who only speak indigenous languages; A group of American exchange students in Italy meet African migrants who risked their lives to make it to Europe; Why Chinese Sci-Fi is gaining in popularity around the world; And Kenyan musician JS Ondara on how Bob Dylan changed his life and inspired his journey to America.
