Inferno Trailer

Professor Robert Langdon wakes up in a hospital feeling terrible and suffering from serious nightmares. His dreams are lifelike and appear to predict a vicious and unprecedented attack on humanity. As the professor begins to come around, his nurse, Sienna, is on hand to treat his head injuries and inform him of his concussion and the side effects he might experience.

Before he can fully understand what brought him to Italy - Langdon's last memories were from Harvard University - a woman enters the hospital and kills the professor's doctor.  With the help of Sienna, Robert escapes and the pair retreat to Sienna's apartment. Whilst searching his pockets Langdon finds a vile with a hazardous label on it.

The vile is the start of Langdon's latest mission, he must find the source of a deadly virus that is thought to be capable of killing half the world's population. Without knowing who's on his side, it looks like Langdon is being hunted by multiple organisations all wishing to cash in on the powerful weapon.

The man behind the toxin and its inevitable release is Bertrand Zobrist, a genetic scientist who has been lauded many times for his advances in his field but also with an unhealthy interest in Dante. Zobrist is dead and now Langdon is the only person who might be able to figure out his true intentions and find the answers to questions being asked.

Inferno is the fourth book by Dan Brown and the third film in the series to be adapted by Ron Howard.
