Who can help me explain mission impossible 1? Thanks!

Synopsis: Jim, the lieutenant of the IMF, a special action group, together with his wife Claire and Ethan, a camouflage expert, successfully identified an old crafty enemy spy in Kiev. His next task is to go to Prague to root out the traitor golitsyn. To this end, the headquarters specially allocated him five members, including Claire Ethan. In Prague, Jim planned to lure golitsyn with a fake Noc list about deep-seated spies, but something unexpected happened. Three of Jim's men and golitsyn died for no reason, and he himself was injured. Ethan, who survived, was surprised to learn from the head of the headquarters that the operation was a trap, with the aim of finding out the real traitor in the IMF. In order to prove his innocence and find out the real traitor, Ethan quietly returned to Jim's apartment. With Claire's help, he quickly noticed a meeting record of trading information with a female buyer named Max from the computer. The computer showed that Max had offered a high price to buy the real Noc list and used this clue. With the help of Krieger, who was recently recruited by Claire into the IMF, Ethan broke through the numerous checkpoints of the CIA headquarters and got a floppy disk with a copy of the NOC list. Ethan and others rushed back to London overnight. Who is the real traitor? Now Ethan has made his own judgment. Ethan went to the baggage room where Max agreed to deliver the goods as planned, but he didn't leave after collecting the money, but quickly dressed himself as Jim in the same place. He wanted to verify his judgment himself, and Claire, who had hurried to meet her husband, mistook Ethan for Jim. His words and deeds exposed his identity as a traitor. Just as Ethan was dealing with Claire, the real Jim appeared. After a fight, Claire was killed and Jim fled to the roof, where Krieger was flying a helicopter to meet him. Seeing that the traitor was about to slip away, Ethan used his quick wits to connect the helicopter with the train, so that Krieger drove the plane into the tunnel with the train. After a thrilling contest, Ethan finally got rid of the traitor and proved his innocence. Mission Impossible has been translated into Mission Impossible, which is a thrilling feature film produced by American Paramount Film Company in 1996. The film tells the story of Ethan, a camouflage expert, who finally eradicated the traitor in the same action group, that is, the "spy". The plot of the film is ups and downs, and the thrilling scenes are endless, which can be described as exciting. Director de Palma obviously used the expression technique of Hitchcock, a psychologist, which made the interlocking and varied story process feel confusing and unpredictable. In fact, the story itself, that is, the anti-espionage of spies to identify traitors within the spy group and eradicate them, has long given the film a hazy and turbulent plot. Coupled with the director's successful use of superb suspense techniques, it has produced extraordinary thrilling effects. The action group went to root out traitors, but they didn't know that the real traitors were among them; Team member Ethan went to look for computer files, but the woman who helped him enthusiastically was the target he was looking for-the real traitor. In addition to the film director, the protagonist's own future is uncertain, and the audience can't judge his fate. Then, only in the progress of time, relying on the layer-by-layer progress of the film's plot, one mystery is revealed to the audience for the second time. These thrilling suspense, such as guessing contests, keep the audience in a state of speculation and high tension, which is of great benefit to the full display of the thrilling charm of the film. Tom Cruise, a world-famous movie star, plays the role of Ethan, a camouflage expert with both wisdom and courage. In the film, Cruise got an abnormal crew cut, showing another cool charm besides his usual comeliness. It can be said that his participation has added a lot of color to this already moving film, and this film has therefore become the dark horse at the box office of American cinemas that year.

By the way, Mission Impossible 1 is not as good as 2 and 3.
