At a time when many white South Africans viewed their black neighbours as inferior, conversely, millions of African women became trusted members of Afrikaner families through their roles as children's nannies. This film follows South African-born Mark Rossiter, whose family left the country in 1986 to live in Britain, as he returns in the hope of finding Susan - the 'second mother' he hasn't seen for 25 years. Armed with only a single photograph and some vivid childhood memories, his search seems futile until an advert in a local newspaper produces a promising lead. (postponed from 15 January)
