Jack Ryan(Chris Pine) is a CIA Financial Analyst whose work leads to the uncovering of a Russian plot against the United States. He is then recruited by Harper(Kevin Costner), another agent, to help stop the plot. Not only does he have to contend with the question of who he can trust, he has to decide what to tell his fiance Cathy(Keira Knightley), who he's kept in the dark. He must also contend with the powerful Russian businessman who is masterminding the plot. If Jack fails, it could mean millions of lives.
The story is well-written and suspenseful, with plenty of action. There is some violence, but only as appropriate to the story, not overdone, as is so common today. It will keep you on the edge of your seat.
