	Synopsis: Commander William T. Riker is charged with hosting Klingon commander Kurn, who takes his place as first officer as part of an exchange program. As expected, his ruthlessly authoritative command style gets on everyone's nerve, but the worst is yet to come: Kurn reveals himself as Lieutenant Worf's younger brother, and demands he joins him in dealing with a blood feud, as their late father's honor is challenged by accusations of treason to the Empire in league with the Romulans during a bloody attack. The Enterprise sets course to the Klingon first city, while Picard fears legal and diplomatic repercussions. Data finds indications the Klingon records were doctored, possibly at Klingon High Council level, so the Enterprise crew sets out to find out the truth...
