Rodolfo Peñareal is obsessed with having a male child. After many miscarriages, his wife Blanca is pregnant again. One night, a girl is born, but they believe that she was born dead. In the same town, in another, more humble house, a boy is born, but his mother dies during labor. The midwife and the nanny of Blanca, with their best intention and with the aim to calm down Rodolfo, decide to exchange the children. (Wikipedia)
