The USS Enterprise NCC 1701 detects time disturbances centred around a deserted planet. Mr Sulu is injured on the bridge and Dr McCoy saves his life with just a few drops of cordrazine. However, McCoy accidentally suffers an overdose when the Enterprise experiences another time displacement and injects a full vial of the powerful drug cordrazine into his bloodstream causing him to go beserk. Bones beams down to the planet below amidst the remains of a ruined city some 10,000 centuries old. In the grip of complete madness, he evades the enterprise crew yet again and leaps through a strange arch pulsating with power. The Guardian of Forever identifies itself to Kirk and Spock summarizing their predicament.
"Your vessel, your beginning. All that you knew is gone." Dr McCoy has gone back through time and changed their history! Their world no longer exhists! Uhura reports dead communicator contact with the ship. Fortunately, Mr Spock's tricorder was recording the Guardian's past timeline events, right at the point, McCoy dived through the portal giving them a chance to rectify the damage done. I love how Spock manufactures a computer from his tricorder that shows how history will unfold if the focal point in time, Edith Keeler, lives.

My friend is obviously Chinese. I see you've noticed the ears, they're actually easy to er explain" Kirk looks to Spock with a lost look on his face.
"Perhaps the unfortunate accident I had as a child." prompts Mr Spock.
"The unfortunate accident he had as a child, he caught his head in a mechanical rice picker."
This is a great moment when Kirk and Spock face a 1930's policeman who isn't convinced with the captain's rice picker bluff. Now I wonder why?
Live long and prosper, trekkers.
