Newly appointed CIA acting director Jack Ryan is up against a potentially catastrophic merger between a drug cartel and a terrorist organisation in the latest trailer of Tom Clancy’s Jack Ryan Season 4.

Dropped by Prime Video on Wednesday evening, the two-minute-17-second-long trailer follows John Krasinski’s Jack as he is tasked with unearthing internal corruption, and in doing so, he 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 threat — the merger of a drug cartel with a terrorist organisation. The investigation ultimately reveals a deep conspiracy and tests Jack’s belief in the system that he has always strived to protect.

“Convergence has begun. Watch the trailer for The Final Season of Tom Clancy’s Jack Ryan arriving June 30,” tweeted Prime Video, sharing the trailer on the microblogging site. .

“Here. We. Go! Jack Ryan final season. Begins June 30th,” Krasinski wrote alongside the trailer on Twitter.
