In Canada many women volunteer to give birth to a stranger's child and do not get paid in return. Under Canadian laws, gestational surrogates receive only expenses in exchange for getting pregnant and carrying a baby for nine months. But, why do they do it? We meet the surrogate women to find out. We follow them as they navigate the emotional challenges of giving life to a baby that they will say goodbye to after birth, and we meet the families who will welcome home these special babies.
