The governor of California is attacked during a visit to Los Angeles with his daughter and aide, and barely escapes with his life. Taken to the de la Vega house to recover, he is much too weak to travel for several days. The aide, Capitan Arrellanos, tells Diego he suspects the attack to be the work of the Rebatos, a group that wants to sever ties with the government in Spain.

Capitan Arrellanos refuses to help the Rebatos any longer in their attempts to kill the governor. Instead, he chooses another plan designed to make him the head of the government. He asks the governor's daughter to declare her father too ill to continue in office. Furious at this request, Leonar refuses to cooperate. She then tells her father of the aide's plot.

Capitan Arrellanos continues his attempts to rule California by hiring Carmelo, a recent arrival to the pueblo, to kill the governor. Diego and Bernardo overhear the plan but don't act at once, hoping instead to learn who the other conspirators are. The governor has begun to recover and spends his time sitting outside on the patio, which prompts Don Alejandro to give a party to celebrate his better health.

The recovering governor is beginning to become irritated by his confinement to the de la Vega home. At times it seems as if the only thing that can pacify him is a music box. Almost as soon as it begins to play, the governor falls asleep. Knowing that the Rebatos are still trying to kill the governor, Diego uses the box to lull him to sleep then Bernardo moves him to safety.
