Jack Ryan is back for a fourth and final season, with John Krasinski starring as the title character.
The former field agent is back for his 'most dangerous mission yet,' after three action-packed seasons already. The season's official synopsis reads: "As the new CIA Acting Deputy Director, Jack Ryan is tasked with unearthing internal corruption, and in doing so, uncovers a series of suspicious black ops that could expose the vulnerability of the country.
"As Jack and the team investigate how deep the corruption runs, he discovers a far-worse reality—the convergence of a drug cartel with a terrorist organization—ultimately revealing a conspiracy much closer to home and testing our hero’s belief in the system he has always fought to protect."
