In a world where hearts are as fragile as glass, a masked young man presents himself in an emergency room, dressed in an elegant period outfit and claiming to be the legendary lover Don Juan. Portrayed by the charismatic Johnny Depp, this romantic dreamer lives in a reality where love and passion dominate each of his days. His fervor for women and his unparalleled gallantry captivate everyone, including the skeptical psychiatrist played by Marlon Brando, who finds himself trapped in his own monotony.
The doctor, surprised by Don Juan's stories, begins to question his own life. As he tries to help the young man demystify his madness, he is drawn into a journey of self-discovery, reflecting on his own romantic frustrations and loss of passion. As Don Juan shares his true story of love and loss, his vibrant spirit inspires the psychiatrist and teaches him to rediscover the spark that once kept his heart alive.
Through intertwined encounters with different women who have been part of Don Juan's life, the plot explores themes of true love, idealization, and the fragility of human relationships. In a dance between reality and fantasy, both men confront what it means to be a lover in a world that often feels empty, and one man's journey helps the other find a new purpose and hope.
