Abandoned at the age of three, Hortensia is raised by three peasants to serve the greater good of others. As Hortensia matures, losing her naivety and innocence, she realises her role in the game plan and fears for her unborn son. Her intention to provide her son with a secure future fails. She breaks her one promise - she gives him up. In return, she gains a girl who she raises as her own. When life starts to go as planned, her son's biological father, a past lover and a man desperate to make her his lover, threatens all she has striven for. To save her children, herself and the valley's livelihood, Hortensia must make the biggest sacrifice of all.
