Conviction is set two years after Splinter Cell: Double Agent, which saw series hero Sam Fisher become a fugitive from the FBI, NSA, and an alphabet soup of other agencies. In the course of investigating his daughter's death, the now-grizzled Fisher discovered that his former employer, the covert organization Third Echelon, has double-crossed him. Avoiding capture, he travels to Washington, DC, to uncover the conspiracy that led to his undeserved disgrace.
