Susana Trejos, a responsible doctor devoted to her patients, is about to marry Andrés del Valle, a lawyer with a shady past who carries on a secret affair with Ivonne, a hypocrite who claims to be Susana's best friend.
Susana is in love with Andrés, but he only wants to marry her to kill her and inherit her fortune.
Mere hours before her church wedding, Susana receives a message that Andrés is in the Lacandon Jungle, gravely ill and near death.
True to her nature, Susana decides to fly by helicopter to save her beloved, only to find an archaeologist with the same name as her fiancé.
She reveals herself to some family members, but keeps her survival hidden from lawyer Andrés, so she can initiate a divorce after discovering his affair with Ivonne and his takeover of her assets.
