Jim Phelps (Voight) and his team charged with stopping a traitor from stealing and selling classified material. Everything was going well until the man they are following and all of the team are inexplicably killed except for Ethan Hunt (Cruise). Ethan then calls the Director and goes to meet him when he discovers that the whole mission was to ferret a mole that they have been suspicious of for some time. The Director shows evidence that hints that Ethan's the one they have been looking for but Ethan knows that he is not, so he escapes. Ethan then arranges to meet the buyer and whom he warns against using the material he has and when they meet he offers to get what he paid for in exchange for telling whom the mole is. Ethan, along with Phelps' wife Claire (Beart) recruits two disavowed agents to help him which won't be easy.
