Paula Sanchez was jailed and tortured by Augusto Pinochet's notorious secret police in Chile, so when her son told her his friend's father was part of the regime and lived a few suburbs away in Sydney, she shut down.
Detained for two months in 1987 at a jail in La Serena, 500 kilometres north of the capital Santiago, the leftist activist was interrogated, tortured, electrocuted and raped by four men working for the powerful security agency.
