The series starts twenty years earlier when a group of Chilean friends travel for fun to Los Angeles, United States. One night in the hotel a gunshot is heard, and Marcia Jones (Jael Unger), the first to hear it, runs to the room where she heard the shot to find her friend Patricia dead on the floor of the room. Marcia picks up the gun by accident, therefore becoming the sole murder suspect. Months later she's found guilty and sentenced to 20 years in prison in the United States. During the trial it's discovered that at the time of her death, Patricia was pregnant. Every friend Marcia thought she had shuns her, including her husband Esteban San Lucas (Walter Kliche), who leaves her in the United States and forces her to sign a marriage annulment.
