London’s Saatchi Gallery has been transformed into a Russian-style prison through immersive theatre. Political artist and Pussy Riot founder Nadya Tolokonnikova devised the show, she spent two years in a Russian jail after her group’s anti-Putin protests, and is now fighting for prison reform. Before he worked on this programme Channel 4 News’ Kieron Bryan was also arrested and imprisoned in Russia when he was filming a Greenpeace protest in the arctic ocean. He went to meet Ms Tolokonnikova to discuss their own personal stories.
