One of Star Trek's classic tales sports our first look at Spock's parents, Andorians and Tellarites, Federation debate, terrorist raiders and covert assassins -- and the Remastered edition brings its special snap to all. With one envoy murdered and Spock's father Sarek the chief suspect until he has a heart attack, it takes a ruse by Kirk and McCoy to get the stubborn Spock into Sickbay to give blood for his father's surgery after Kirk is stabbed and unable to command. The Remastered version features an all-new detailed shuttlecraft landing in the hangar bay and the Orion spy ship, faithful to the original but finally seen in detail -- as well as the Enterprise phaser tracking system which tries to shoot it down.
