JAG - Season 4 Episode 14 : Webb of Lies 2005

When Harm and Mac set out to find C.I.A. Agent Clayton Webb's killer after his body is found aboard a burning ship, they inadvertently uncover a rogue government spy agency. Retracing Webb's steps, Harm and Mac learn that he was on a top-secret mission to deliver a high-tech weapons project to the proper authorities when he was stopped. Waiting for Harm and Mac when they discover this, though, is none other than Harm's former nemesis, ex-C.I.A. Agent Clark Palmer, now working with the rogue spy agency, who will stop at nothing -- including Harm's murder -- to get his hands on the top-secret project.
