The Searcher leaves Earth to a new mission when Admiral Asimov is ordered to return to the orbit of Earth and wait for Commissioner Bergstrom and his team at the dock station with Buck Rogers. When he arrives, he arrests Buck Rogers for the surprise of his friends and crew. On the next morning, a court is mounted on board of the Searcher and Buck is accused of treachery and one of the responsible for the nuclear holocaust in 1987. They have just found a wallet with a VCR recorded by Buck's best friend Major Peterson that shows Buck with a group of military conspirators' officers that want to begin the war. Buck has no recollection of the event and Dr. Goodfellow proposes to use a probe to retrieve his memories and prove his innocence.
"Testimony of a Traitor" is another good episode of "Buck Rogers in the 25th Century". The episode begins with a serious accusation to Buck Rogers since his prosecutor has jumped to a conclusion without hearing to his defense. The end of the show, with Commissioner Bergstrom asking for pardon to Buck Rogers, is excellent. My vote is seven.
