Children stolen by their parents' killers during Argentina's dictatorship are finally being reunited with their families. Imagine being told your parents are not your real parents. Even worse, the people who raised you had in fact helped to kidnap, torture and murder your real mum and dad. It's the truth facing as many as 500 people born during the late 1970s in Argentina, when the country's military dictatorship detained and killed thousands of political opponents. After their parents 'disappeared', the children were given away to supporters of the dictatorship to raise as their own. Video journalist David O'Shea has been to meet a group of determined grandmothers leading the fight to reunite those children with what's left of their families, and he hears the stories of some of the 101 stolen babies reunited so far.
