Ysabel is a single mother to her loving daughter Maymay. She works as a personal assistant to Scarlet, a socialite. However, Scarlet cannot bear a child so she convinces Ysabel to become her surrogate. And because Ysabel needs money for her daughter Maymay's bone marrow transplant, she agrees to Scarlet's proposal.

Halfway through Ysabel's pregnancy, Maymay unexpectedly dies from an accident. Falling into depression and loneliness, Ysabel cops out on her agreement with Scarlet, flees with the baby and decides to raise her as her own, calling her Maya in memory of her daughter who passed away.

On the other hand, Jonas is a bachelor who secretly has feelings for Ysabel. His love for her turns into hatred when she takes away Scarlet's child who is also the grandchild of his aunt Matilda.

With Ysabel and Scarlet's battle to win Maya, who has the real rights over the child? The mother by blood or the mother who gave birth to her? Is blood thicker than love?
