Giovanni falls in love with Beatrice, the beautiful daughter of Dr. Rappaccini, who has confined her to his poisonous garden. Giovanni visits Beatrice daily in the garden through a private entrance. However, Beatrice has been exposed to so many toxic plants that her body and breath have become poisonous. In an attempt to cure Beatrice so they can be together, Giovanni gives her medicine provided by Dr. Baglioni, but it ends up killing her instead of removing the poison from her system.
