The story begins years after the events of Mission: Impossible – Fallout (2018) , with Ethan Hunt and his team—William Brandt (Benedict Cumberbatch), Luther Stickell (Ving Rhames), and Benji Dunn (Simon Pegg)—facing a new global threat. A mysterious terrorist organization, the Gray Team, infiltrates the IMF with advanced artificial intelligence (Dead Reckoning) and seeks devastating bioweapons. The IMF must thwart the mission while navigating internal betrayals, time-sensitive deadlines, and lethal adversaries. The narrative escalates as Ethan uncovers a personal connection to the plot, forcing him to confront his past while protecting his team, including his wife, Julia Meeks (Samantha Morton).
