It is estimated some 50 million people are living in modern slavery; 10 million more in the last five years. This includes millions in forced labour and forced marriage; with women and children being especially vulnerable. Annette Young talks to Grace Forrest, the founding director of Walk Free, an international human rights group focused on the elimination of modern slavery. Also we meet the women in Venezuela who have taken their futures literally into their own hands and are building their own family homes as the country confronts a housing crisis.
