After she performs with her band for them, a humble young woman becomes part of the lives of five wealthy siblings, and falls for the eldest.
Florencia Fazzarino is a poor girl but her personality is worth millions. She is funny, energetic, and superstitious. In her early 20s she finds herself the new nanny of the Fritzenwaldens, a German family of five orphans. The eldest, Federico, is in charge and his strict education and behavior soon clashes with Flor's style, making her call him 'Freezer'. He has a girlfriend, Delfina, whom everyone calls the Witch because she and her mother Malala are always doing mean things to them. But Florencia's behavior and energy distract Fede from Delfina and he 'melts' over time, and he and Flor fall in love with each other. Malala and Delfina have an economic interest in Federico because when Delfina's father died, he left them with no chance of claiming the inheritance money unless they find his secret illegitimate daughter. Delfina's main target is Florencia, the threat to her only chance of being rich again.—sonia borbor
The series tells the modern fairy tale of Florencia, a Cinderella-in-sneakers. She is a sweet-hearted young girl, who delivers vegetebles and is also the lead singer of her band. The band is contracted by the Fritzenwalden family for their party, organized by the five Fritzenwalden orphaned children. The party coincides with the arrival of Fred, the older (and bossy) Fritzenwalden brother from Germany. After the younger Fritzenwalden Tomás runs away from the mansion to Florencia's place, a series of misunderstandings turn her into the babysitter of Fred's brothers and sisters. Fred's current girlfriend Delfina and her mother Malala, both equally ambitious, move to the mansion with rogue intentions for the family, as well as for their kinder babysitter. For their desperation, Florencia is the lost heiress of the Fritzenwalden - as well as a romance inevitably starts to grow between her and Fred.
