The next-generation Russian submarine Sevastopol employs an advanced AI for testing a new navigation system that uses dead reckoning. The AI tricks the crew into firing a torpedo and then turns the torpedo back on the submarine, sinking it and killing all aboard.
IMF agent Ethan Hunt is assigned to retrieve half of a cruciform key from Ilsa Faust, on whom the IMF has placed a bounty. He travels to Saudi Arabia to obtain the half-key from Ilsa. He then infiltrates a meeting of leaders of the U.S. Intelligence Community in Washington, D.C., including CIA Director Eugene Kittridge and Director of National Intelligence Denlinger, to discuss the rogue AI. Calling it the Entity, they recount how it has achieved sentience and infiltrated the major defense, military systems, intelligence, and financial networks of the world. World powers compete to obtain the key to protect their national security and control the Entity, though the exact means of controlling it are unknown. Believing the Entity poses too great a threat to humanity, Ethan seeks to destroy it.
He and his teammates Benji Dunn and Luther Stickell travel to Abu Dhabi International Airport to intercept the holder of the other half-key. Ethan evades U.S. agents as well as Gabriel, an Entity liaison with ties to Ethan’s pre-IMF past, while the half-key is stolen by a professional thief named Grace. Luther identifies a suspicious piece of baggage; Benji finds what appears to be a nuclear explosive, but finds it empty after narrowly defusing it. Ethan pursues Grace to Rome. After a lengthy chase, Grace escapes again, while Ethan reunites with Benji, Luther, and Ilsa.
