When Harm, Mac and Bud are ordered to run a routine background check on a Navy SEAL who is a candidate for the Medal of Honor, they uncover unsavory information that may make him unworthy.

Lt. Rivers is up for a medal after he single-handedly rescues the undersecretary of state from fundamentalist terrorists. Harm and Mac, in their investigation, find Rivers, an African-American, to be a very tough, complex and uncommunicative individual who is totally devoted to his country and his duty. But his men paint a different picture of him as a gung-ho loner who doesn't care about the safety of his team and, in fact, botched the mission by leaving one of his men behind. Rivers finally agrees to open up to Harm -- but only if Harm can withstand arduous SEAL training for one day -- including the brutal manhandling required of the ""hostage interrogation.""

When Navy SEAL Medal of Honor winner Lt. Curtis Rivers is fired upon while on a training mission, he returns fire only to discover that he has shot a seemingly unarmed 14-year-old boy. During Harm and Mac's investigation, they discover that the boy may have been accompanied by his uncle, a fugitive wanted by the F.B.I.

When Rivers goes AWOL to track down the fugitive and is captured by separatists, Harm and Mac find themselves not just investigating the case, but trying to defend Lt. Rivers in a court that does not recognize the U.S. government and its laws.

Lt. Curtis Rivers (Montel Williams), a Medal of Honor-winning Navy SEAL, is court-martialed for punching a Congressional candidate who falsely claims to be a Navy SEAL. Rivers explains that he is on a crusade to expose Navy SEAL impostors.

In order to prove his point to Harm, who is assigned to defend him, Rivers places him in the center of a dangerous plot to expose another false SEAL. Though Rivers assures Harm that his safety is in the hands of two legitimate former SEALS, he finds himself alone in court when Harm misses the trial to pursue a lead on the would-be assassin.
