In April 1977 a group of women in Argentina held the first ever public demonstration to demand the release of thousands of opponents of the military regime. It was the start of a long campaign by the women, who became known as the Mothers of the Plaza de Mayo. Also on the programme: the controversy surrounding Syria's presence in Lebanon, plus the pioneer of psychotherapy RD Laing, Bulgaria's attempts to crush Turkish language and culture, and we hear the shocking testimony of a survivor of Bosnia's notorious rape camps.
