However, she is not interested in government. Obsessed with her husband, Joanna surprises him in bed with a lover, who Joanna later successfully identifies as Inés de Brabante, one of the court ladies. In a fit of jealousy, Joanna cuts the hair of her rival. While Joanna despairs at her husband’s unfaithfulness, she receives further bad news. Her mother has died. Joanna thus becomes Queen of Castile and has to return to her kingdom. Her tantrums over her husband’s infidelities have made her start to become known as Joanna the Mad. At the Castilian court in Burgos, the Queen is happily greeted by her subjects, but her marital life is still in turmoil. Philip is soon bewitched by the charms and spells of Aixa, a Moorish prostitute who uses her sexual attraction and black magic to secure Philip's favour. With this new lover, the King becomes noticeably indifferent toward his wife, which adds to her increasingly insane jealousy. Against the background of this troubled marriage, there are two opposed political parties at court, one Flemish, the other Castilian. The conspiring Flemish usurpers are headed by Señor de Veyre, Philip's right-hand man. Their objective is to have Joanna declared insane and for Philip to take power away from her. Joanna has her own set of supporters, the loyal Castilian royalists, headed by the Admiral of Castile. The Admiral and the Queen's friend and confidant, Elvira, try unsuccessfully to rescue Juana from her marital obsessions. However, it is not the government that is on the Queen's mind; she is fixated on retaining her husband’s love. To avoid any temptations at court, she hires only ugly-looking maids of honour to serve her, but in fact Aixa has been brought to court by Philip, passing as one of the court ladies under the name of Beatriz de Bobadilla. Unaware of this, the Queen relies on Beatriz to find a spell to help her retain her husband's love. Joanna is equally misguided in her attempt to regain Philip's attention by simulating a love affair with Captain Álvaro de Estúñiga, a close friend from her childhood. The Queen’s lack of control permits the manipulation of her enemies to have her declared incompetent to rule. The King, encouraged by Señor de Veyre, resolves to take the rule of the kingdom for himself and shove Joanna out of the way. He finds an unlikely ally in Joanna's own
