Peru has long struggled with political, cultural, racial, and economic divides, a source of tension that propelled the leftist former schoolteacher Pedro Castillo to the Presidency last year.

Finnish journalist Kukka Maria Ahokas has little trouble crossing this and other barriers, and she introduces us to activist Carlos Hinostroza, who is trying to tear down the wall for all.
