On a flight back to Buenos Aires, the millionaire Fernández Salguero family, their young daughter, Clodine, and servants, are stranded in the jungle after their jet malfunctions. The only survivors are Clodine and servants (the Benítez family), one of whom has a daughter of similar age (Lorena). They decide to abandon Clodine in the wild and tell their own young daughter to take the identity of Clodine in order to get her inheritance. They manage to convince her grandmother, Amanda Fernández Salguero, that Lorena is actually her granddaughter.
20 years later, the news reports the findings of "a young girl of the jungle" who was raised by monkeys. Responding to the name "Asai", she appears to have survived in the wild for the last 20 years. Amanda, stirred by the memory of the tragic loss of her son and daughter-in-law, invites "Asai" to live with her, and the secret of the Benítez family is threatened by her appearance.
