They were institutions for so-called fallen women and young girls. As Catholic institutions, they were run by Catholic nuns. They were meant to be for women who had been prostitutes and young girls who had become pregnant without being married. The text that accompanied this film stated that the institutes had been named for St. Mary Magdalene, who according to Catholic tradition, repented her sins and became one of Jesus' closest followers.
The movement soon became distant from it's original aim which was to be a sort of rescue movement for these women and the institutions soon took on a prison-like regime. The women and girls who lived there, were locked in, and frequently beaten by the nuns for disobedience as they were deemed to be 'in need of penitence'. In order to enforce and maintain a monastic atmosphere, the inmates were required to observe strict silence for most of the day. In a place that defined belief their only hope was in each other. The film was very moving and for someone who, being very tired, was only going to watch the first few minutes, ended up rooted to the sofa and watched the whole thing.
As the brief widened, it extended beyond prostitution and unmarried mothers to developmentally-challenged women and abused girls. Sometimes, young girls considered to be too promiscuous and flirtatious were sometimes sent to the laundries/asylum for just those reasons.
