The story begins when Cielo, a circus acrobat, and Nico, an archeologist obsessed with finding Eudamón Island, stumble into the lives of a group of orphans who are being exploited by Bartolomé and his housekeeper Justina. Cielo and Nico will help and rescue these kids, while they discover the Inchausti Mansion's gloomy secrets, which are linked to Cielo's past and to Eudamón. In that mansion, Bartolomé acts as director of the BB Foundation, which he uses as a cover for his horrible plans, which are threatened by the emergence of the heirs, Ángeles and Luz Inchausti.

No longer being subjected to Bartolomé's evil reign, the kids can live a normal life in the now Hogar Mágico (ex BB Foundation) ran by Nico and Cielo, who is missing after being absorbed by the mansion's clock. New kids join the home and the CC Corporation (CC) emerges, led by Juan Cruz, a fallen angel, a ghost, obsessed with returning to Eudamón and with Cielo, who, like him, was able to get to this other plane. To meet his objective, Juan Cruz, together with Franka and Charly, will try to emotionally break those who live in the mansion and will try, restlessly, to prevent Cielo from having her daughter, Paz.

The kids and Justina time travel and show up in different places, 22 years in the future, after opening the book with the seven locks. With Paz, Hope and Camilo's help they'll have to figure out their mission, saving Paz, Nico and Cielo's daughter. Paz is a restless, disobedient, liberal, protective girl with a maternal spirit who falls for Camilo Estrella, Mandalay's new principal. After being unable to prevent Paz's birth, Juan Cruz will try to murder her 22 years later to go back to Eudamón. There's also resistance to the dictatorial government led by the Chief of Ministry.

Having saved Paz meant to succumb to a big time paradox, where the Chief of Ministry deployed the "Little Prince" protocol. From then on, the kids couldn't go back to their time and were separated. Many were captured by the Government Corporation, reset and taken to what once was Mandalar, now called "NE School" (acronym for "New Era"). Others form "the Resistance" and will stop at nothing to achieve their new mission and go back home.
