The CIA issued an instruction to the special agent team headed by Jim that an agent has been treasoned and will steal the list of CIA agents lurking in Eastern Europe at the Prague consulate. Once it falls into the wrong hands, the consequences will be disastrous. They were ordered to obtain evidence that the agent had stolen intelligence and arrest him and the buyer. Soon, under Jim’s plan, the front-line main force Ethan Hunt and several other members were all in place, but when the plan was halfway through, the situation suddenly took a turn for the worse. The team members including Jim were killed one after another, the intelligence was missing, only Ethan survived. Ethan, who was almost mentally broken, met with his boss, but was accused of being a traitor because he was spared from death and the account was suddenly extra 120,000 US dollars. It turned out that false information was stolen, and the real purpose of the operation was to detect the rape. Ethan, who stood out from the siege, decided to find the traitor. At this time, Jim's wife Claire, who also survived by chance, reunited with Ethan.
After getting in touch with the buyer Max, Ethan promised that he could get a list of agents, under the condition that in addition to 10 million US dollars, he must surrender the insider. Ethan found two suspended agents of the CIA, and a group of four sneaked into Langley's headquarters, successfully stealing intelligence. Ethan, who rushed to London, suddenly met Jim. Under Jim's lie, Ethan gradually sorted out the context. Jim and Claire should be the real murderers behind the scenes. Soon, Ethan, Max, Jim, and the CIA gathered on the intelligence train for a desperate fight. After a thrilling confrontation, Ethan finally got rid of the insider and returned to the ranks of agents.
