Ethan Hunt (Tom Cruise) goes rogue once more when a face from his past, a man named Gabriel (Esai Morales), resurfaces due to working with a mysterious AI known as The Entity, which can manipulate computer programs for malicious purposes. Gabriel is after a key that The Entity wants, and a thief named Grace (Hayley Atwell) takes one half from Ethan after he gets it from Ilsa Faust (Rebecca Ferguson).
Ethan pursues Grace, with help from Benji Dunn and Luther Stickell (Simon Pegg and Ving Rhames). Gabriel is helped by an assassin named Paris, but she changes sides after Ethan spares her life. After learning Alanna Mitsopolis/White Widow has the other half, Ilsa is killed by Gabriel when she tries to protect Grace.
Ethan and Grace make it onto the Orient Express where Alanna is selling the key to IMF director Eugene Kittridge. Gabriel kills the conductor and forces the train to go at high speed toward a bridge he has rigged to blow. Ethan fights Gabriel, but he escapes after an agent named Jasper Briggs and his partner Degas stop Ethan from killing him. They save the passengers as the bridge blows, and a wounded Paris saves Ethan and Grace.
Ethan escapes and reunites with Benji after taking the key from Gabriel. Grace joins IMF while the next mission is to find the Russian sub carrying The Entity, and either control it or destroy it.
