John Krasinski embarks on his last mission in the Jack Ryan season 4 trailer. Premiering in 2018, the Prime Video series has reinvented Tom Clancy's iconic character across three seasons. Jack Ryan season 4 will premiere on June 30 and bring the show to a close with six action-packed episodes.

Now, Jack Ryan season 4.

The trailer reveals that Ryan will be dealing with one of his deadliest and most insidious threats yet. When a major political figure is assassinated and there's evidence that the CIA may be involved, Ryan works with a dangerous new operative - as well as a few familiar faces - to get to the bottom of a vast conspiracy that combines a drug cartel and a terrorist cell.

Everything We Know About Jack Ryan Season 4

As the conclusion to the series, Jack Ryan season 4 is set to pull out all the stops. This brand-new threat is both foreign and domestic, which means that Ryan's clandestine search for the truth will potentially be tied up with miles of red tape. It seems inevitable that the identity of the person behind this conspiracy will be explosive, ripping a hole in the fabric of the CIA as Ryan knows it.

On the scene this time is Michael Peña as the hard-nosed Domingo "Ding" Chavez, a far cry from his typical comedic roles in films like Ant-Man or CHiPS. However, Ryan will ally with a few familiar faces from seasons past, including Betty Gabriel's Elizabeth Wright, who first ed the Jack Ryan cast in season 3. Also back on hand is Michael Kelly's sardonic Venezuela station chief Mike November.

Jack Ryan season 4 will premiere two episodes at a time, running through July 14. With only three weeks worth of episodes set to air, it is certain to bring shattering revelations. Considering the fact that there are more than three dozen Ryanverse novels for it to pull from, it's difficult to predict where the season will end beyond having massive consequences.
