Throughout 2003, she starred in the musical adaptation of the book by Antonio Velasco Piña, a musical that tells another version of what happened on 2 October 1968, in Tlatelolco. Lucero decided to take this play since she rejected to participate in the telenovela Amor real. Several months in theaters made her win an award for best actress in a musical and offered 100 performances with 100 standing ovations from the audience. Critics and reporters who were reportedly hostile to the actress created a situation whereby, when the plaque for the 100th performance was shown, television reporters insisted on having an interview with the actress and tried to follow her, only to have a security guard draw his gun against them. She defended the acts of her guard which led to her being removed from hosting the annual Telethon for several years.
