"Day of the Dove" is the seventh episode of the third season of the American science fiction television series Star Trek.
The Federation starship Enterprise responds to a distress call from a human colony, but on arrival finds no signs of any type of inhabited settlement.
Kang surrenders and he and the other Klingons, including his wife Mara, a science officer, are escorted to secure quarters on the ship.
Meanwhile, a glowing entity composed of pure energy, which had initially emerged on the planet below, enters the Enterprise undetected and interfaces with its controls.
When informed by Lt. Sulu that Chekov never had a brother and is an only child, Kirk realizes that the entity is capable of implanting false memories in order to trigger aggression.
Kirk believes that if he can get to Kang, the Klingon commander can help stop his crew from fighting and help return the ship to a normal state.
As they clash, and with the entity hovering and pulsating a bright red nearby, Kirk implores Kang to stop, telling him that they may become its puppets for a thousand lifetimes if they continue to fight.
Aside from remastered video and audio, and the all-CGI animation of the USS Enterprise that is standard among the revisions, specific changes to this episode also include: Zack Handlen of The A.V.
