This is the first episode in the Worf-Duras story arc and shows how true Worf is to Klingon ideals - truer than other Klingons, in fact. Captains Log Stardate 43865.2: The USS Enterprise rendezvous with a Klingon cruiser to take on a Klingon commander, Kurn, who has been temporarily assigned to the Enterprise as acting first officer as part of the Federation-Klingon Officer Exchange Program. (Earlier, on Stardate 42506.5, Commander and Enterprise First Officer William Riker served in a similar capacity aboard the IKS Pagh.) Kurn immediately tries to impose "Klingon-style" discipline aboard the Starfleet vessel, with Captain Jean-Luc Picard's full approval. The surprised crew find Kurn's methods excessively harsh and draconian.
