Max Pearson presents a collection of the week’s Witness History episodes, all with an Argentine theme.

We find out more about the 1985 ‘trial of the juntas’ when the country’s former military leaders stood accused of torturing and murdering thousands of their own people. And we hear from historian Dr Victoria Basualdo about life in Argentina, both before and after the trial.

Also, the story of the grandmothers who championed the study of genetics to find their missing loved ones. And why tens of thousands of protesters took to the streets of Buenos Aires in 2015. Plus, the bizarre story of Eva Peron's disappearing corpse. And finally, more on the Argentine animator who Walt Disney wanted to hire.
