Cristóbal is a handsome, ambitious, and defiant surgeon who never follows the rules; the exact opposite of his partner and friend Santiago, who is a rigid man trapped in a monotonous marriage. For her part, Julia is a woman who, after the birth of her son, abandoned her dreams of becoming a doctor, and without realizing it, ended up saddened, living under the shadow of Santiago and his professional achievements. The three must endure disappointments, betrayals, and situations that are not only very complicated but also hidden behind the perfect lie that they built and have lived under for many years — and the truth is that each one envies the other's life in secret.
