The Final Reckoning is seemingly the end of Ethan Hunt’s story in the Mission: Impossible franchise, but it doesn’t have to close the whole series.

Ethan Hunt is an IMF agent and the main protagonist of the Mission Impossible franchise. Tom Cruise recently portrayed the character, reportedly for the last time, in Mission Impossible: The Final Reckoning. Here's the official synopsis:

Before and after Ethan Hunt arrives on the USS Ohio, the vessel is engaged in a hunt for a rather infamous submarine that’s part of a larger maneuver. As the world is manipulated by The Entity, the lines between peace and war were already blurred enough, and then Ethan Hunt went to supposedly “poke the bear.”
