Despite the hardship, there are those who fight and overcome...

Marta is a single mother and a humble woman who’s doing her best to offer her two daughters, Susana e Beatriz, a good life. But when she finds out that her younger daughter has a rare and serious condition, everything changes in this family’s life. Susana decides to seek out Rodrigo, the child´s father and a wealthy man who can afford to pay the much needed surgery abroad. Even though he didn't even know he had a daughter, Rodrigo accepts to pay for the surgery on the condition that he’s granted custody. Marta is then faced with the greatest dilemma in her life: in order to save his daughter, she’ll have to give her up.

Rodrigo will end up using Beatriz in an elaborate ploy to get closer to Marta. However, his cousin Gabriel’s return to Portugal will make things difficult for him, as Gabriel will fall in love with Marta, thus turning into Rodrigo's rival.
