She is arrested, but not finding sufficient evidence of guilt, the judges decide to investigate her past, when Rosa and Miguel acted in a theater in Madrid and she fellin love with a young doctor, leaving his career for him. This situation has a direct impact on Miguel, which fails miserably with the withdrawal of his partner.
