Muchachitas

Four girls (Mónica, Elena, Leticia and Isabel) enroll in an art academy to pursue their dreams of careers in acting and singing. The four are from different backgrounds:

• Monica is wealthy but humble and sweet. She dates Rodrigo, who works under her father at their supermarket and drives a taxi on the side. When Rodrigo is framed by Monica's cousin Federico and sent to jail for industrial espionage, she stands by him, but she cannot forget her previous boyfriend Roger, who was also the object of attempted murder by Federico.
• Elena is poor and tough. She was Rodrigo's first girlfriend, but Rodrigo dumped her for Monica, causing a rift between the two girls. Later, however, it is revealed that Elena's father is also Monica's biological father; their respective mothers, also active in theater, had been friends and rivals.
• Isabel is middle-class and selfless. She lives with her widowed father. She gets involved with Pedro, who turns out to be married, but though Pedro's terminally ill wife forgives her and entrusts her with the care of their daughter, Betty, she distrusts Pedro.
• Leticia is a middle-class social climber, who is not hesitant to speak her mind and to pretend to get on with rich men. She eventually "marries" Federico, not realizing that the wedding has no legal effect (the license was not properly filed). She is later sent to work for her grandmother, who was also once a social climber but has mellowed and grown wiser.
