Here is the plot summary of Dan Brown’s novel “Inferno”:

The plot of “Inferno” centers around famed Harvard symbologist Robert Langdon, who finds himself in a deadly race against time to uncover a secret conspiracy that could affect the course of humanity.

Langdon awakens at a hospital in Florence, Italy, with no knowledge of how he got there or why he is in such a state. He realizes he is being hunted by an unknown assailant as he tries to put together his recollection.

He quickly realizes he’s been shot, has a head injury and a strange device with a biohazard symbol is implanted in his tweed jacket. This unusual gadget turns out to be a high-tech projector (Faraday Pointer) that displays an updated version of Botticelli’s Map of Hell, based on Dante’s “Inferno.” The map contains hints that lead to Bertrand Zobrist’s creation: an “Inferno” virus that may infect and sterilize a substantial section of the human population. Zobrist, who committed suicide before the novel begins, left a video message in which he reveals his intention to distribute the virus on a specific date.

When Vayentha, an assassin, arrives at the hospital and murders one of the physicians before attempting to murder Langdon, Langdon escapes the hospital with the help of Dr. Sienna Brooks, a clever and resourceful doctor. They flee to Dr. Brooks’ house.

Langdon and Sienna Brooks begin to piece together the clues left by Zobrist. The pursuit leads them to A series of hints leads them to the Old City. They arrive but discover that a team of soldiers and Florentine police are looking for them. They flee, and Langdon analyses the “Map of Hell” once more, noting various alterations in the layers. ‘Catro vace’ is an anagram discovered by Langdon. They elude the troops and enter the Palazzo Vecchio via the Vasari Corridor. They find the line in Vasari’s picture The Battle of Marciano, which is housed in the ‘Hall of the Five Hundred’.

At the Palazzo, Langdon runs into Marta Alvarez, a museum guide who recognises him after meeting him and Ignazio Busoni, the director of the Duomo Cathedral, the night before when she showed them Dante’s death mask. Langdon requests to see the mask again in order to retrace his movements, but the mask has been taken, and security tape shows Langdon and Busoni stealing it. Fleeing, Langdon, and Sienna listen to a message from Busoni about “Paradise 25.”

Langdon and Brooks evade the guards, but soldiers arrive and pursue them throughout the attic. Brooks pushes Vayentha to her death as she attempts to shoot Langdon. Langdon links the phrase “Paradise 25” to the Florence Baptistry, where they discover a Dante mask containing a concealed riddle from the mask’s current owner, Bertrand Zobrist.

Ferris, an agent tracking Langdon, pursues them inside and assists them in evading the soldiers. They follow the solution to the enigma to Venice, where Langdon is captured by soldiers and Brooks escapes.

Dr. Elizabeth Sinskey, the director-general of the WHO, is introduced to Langdon. Invoking the Doomsday Argument, she explains that Zobrist, who committed suicide the previous week, purportedly developed a new biological plague that will render a third of the world’s population infertile in order to solve the problem of the world’s impending overpopulation. Sinskey broke into Zobrist’s safety deposit box, located the projector, and flew Langdon to Florence to investigate the clues. After meeting with Alvarez and Ignazio, he ceased communicating with Sinskey, and the WHO feared he had betrayed them and was working with Zobrist. They were members of the WHO’s emergency response team and had no intention of killing him.

Zobrist had paid the shadowy consulting firm “The Consortium” to safeguard him and his invention until a predetermined date. In addition, he left behind a video with disturbing Dante imagery and a photograph of the plague container concealed underwater. It is a bag that dissolves gently. The video asserts that the world will be different the next morning. When Sinskey recovered it, the Consortium kidnapped Langdon and orchestrated every event leading up to this point to motivate him to solve the puzzle.

Brooks goes rogue, and The Consortium discovers that she was Zobrist’s covert supporter and lover. After Langdon extracted the text from Dorè’s illustration ‘Dandolo Preaching the Crusade,’ she learned where the plague was being held and acquired a private aircraft to get there. To halt her, Langdon, the WHO, and The Consortium join forces. After viewing Zobrist’s video, they determine that the bag containing the epidemic will be completely dissolved by the date specified in the video and that Zobrist’s clues point to the Hagia Sophia in Istanbul. They detect the plague in the Cistern, but Brooks is already there. The bag containing the plague had already been breached, resulting in its global dissemination via tourists. Brooks flees the Cistern, causing a panicked stampede of tourists, while Langdon gives pursuit.

Despite nearly escaping, Brooks returns and discloses that the bag disintegrated a week prior. The date stated in Zobrist’s video was a mathematical calculation of when the entire planet would become infected, which has already occurred. The plague created by Zobrist is disclosed to be a vector virus that randomly employs DNA modification to render one-third of humans sterile. Brooks discloses she attempted to stop the virus on her own because she distrusted the WHO and feared the virus would be weaponized if they discovered it. The commander of The Consortium attempts to evade WHO custody, but is eventually apprehended. Since Brooks has extensive knowledge of Zobrist’s research and work, she is granted amnesty in exchange for working with the WHO to combat the crisis.
