Mission impossible : Dead Reckoning, partie 1 (2023)-Premiere

An all-powerful AI system known as The Entity has gone rogue. Two interlocking keys are the only possible way to control it, and governments across the world are aiming to seize its power.

IMF leader Kittridge calls on Ethan Hunt to find the keys. Ethan retrieves one of the two keys from Ilsa Faust and fakes her death.

Hunt, Benji Dunn, and Luther Stickell attempt to track the other key in Abu Dhabi, but a thief Grace steals it first. While they are being pursued by other U.S government operatives led by Briggs, the team are compromised by The Entity and disband.

Ethan tracks Grace to Venice, where she is bringing the keys to Alanna Mitsopolis. Grace and Hunt are pursued by Briggs, local police, and mercenaries working on behalf of The Entity. They are joined by Benji, Luther, and Ilsa, who explains that the keys can access the source code of The Entity, whose location is only known by one person - the buyer.

Alanna makes a deal with terrorist Gabriel for the keys, who wants to prevent others from controlling The Entity and allow it to take over the world. During a fight, Gabriel kills Ilsa.

Grace disguises herself as Alanna in order to intercept the deal on the Orient Express, so Hunt's team can find the location of The Entity. The buyer turns out to be Kittridge on behalf of the US government.
