Letícia saves the daughter of billionaire César and discovers the secret he hides from the world: a rare medical condition that can only be controlled by the side of a trusted partner. But her own life falls apart when she catches her husband Caio — who pretended to be poor and paralyzed for seven years — cheating on her with Isaura at a party. Divorced, humiliated, and with only her son to protect, Letícia accepts a contract marriage with César in exchange for money. What begins as an agreement between two wounded people turns into real passion, as old secrets threaten to reveal the true origin of César's daughter and destroy the new family they are trying to build.
