"The movie will pick up with the Jack Ryan not long after his stint in the Marines, before he's joined the CIA, while he's a Wall Street stock broker, an occupation that will play heavily into the script. In the Clancy novels, Jack Ryan was a successful financial analyst in Baltimore for Merrill Lynch. In the new movie, he will have transplanted to Moscow to continue his financial advising, not for Merill Lynch (which has been absorbed by Bank of America), but for a billionaire employer. It is that billionaire employer who eventually sets Jack Ryan up to take the fall for terrorist plot designed to collapse the U.S. economy. 

After that, Ryan must race against time to clear his name, reveal the terrorist plot, and save his wife, who has been taken hostage by the billionaire employer."
