In the humble home of that family a girl named Candace Flynn, with a childhood full of upsets. When Candace was just a child, her parents separated, leaving her to care for her mother, who never paid enough attention to her. At the birth of his brother Phineas, who suffered from hyperactivity, and then his half brother Ferb, who was born with a serious case of mental retardation, which among other things prevented him from articulating any word, things went from bad to worse for the correct development of Candace.
