Kirk's name is being chanted loudly as he's brought before a massive assembly hall of Klingons. In case you don't know, Kirk has killed his fair share of Klingons in his day. They don't like him.
Starfleet officers, watching this, call it a "show trial." This must be the murder case.
Kirk and McCoy are represented by someone named "Colonel Worf." This character is a reference to Worf from Star Trek: The Next Generation (and is played by the same actor). Many fans believe this to be an ancestor of that character.
Chang claims that Starfleet officers, wearing magnetized boots, boarded the ship and assassinated his men.
Chang interrogates McCoy and implies that he is either an "incompetent" doctor or a legit assassin. Azetbur looks uncomfortable about all of this.
Chang then accuses Kirk of being the "architect" of this plan. He also quotes Shakespeare. Because of course.
Shockingly, Chang plays the captain's log, in which Kirk blamed the Klingons for the death of his son. How did he get that? This is smelling fishy...
Needless to say, the room goes wild. Chang goes hard in the paint, referencing events of past movies to drive his point home.
Chang rests his case. Ouch.
Kirk and McCoy are found guilty. Double ouch. Colonel Worf angrily says that the evidence is all "circumstantial" and demands that this be taken into account during sentencing.
In the interest of keeping the peace, the judge forgoes the death penalty. Phew. However, the two men will be sentenced to the "dilithium mines on the penal asteroid of Rura Penthe" for the rest of their lives.
Chekov says that Rura Penthe is known as the "alien's graveyard."
Needless to say, everyone on Enterprise is bummed.
Spock asks Valeris to replay the recording of the torpedoes hitting Kronos One. Scotty still thinks that it's impossible that Enterprise fired them.
Spock now agrees. But if it wasn't Enterprise, then who was it?
Chekov suggests that the "neutron surge" recorded before the explosion could have been produced by a ship. Perhaps it was a cloaked Klingon Bird of Prey, Spock suggests, despite the fact that these things usually can't fire weapons when in stealth mode.
Spock determines that someone involved with the plot is aboard the ship—and that this person forged Enterprise's data records.
In order to finds out who, Spock needs to find those magnetized boots.
