A:
The story opens with an immense explosion somewhere in space. Huge shock waves radiate out from the blast site. On board the USS Excelsior, Captain Hikaru Sulu (George Takei) makes an official entry in his log, noting that his mission of "cataloging gaseous anomalies in Beta Quadrant" is over and they are returning to Earth. The ship is suddenly struck by one of the shock waves from the explosion. Sulu orders his crew to restore control to the ship, which is done quickly. Looking over their scanning equipment, the crew determines that the shock wave originated at the location of the Klingon moon Praxis. Sulu remarks that Praxis is the primary source of energy for the Klingon Empire, and orders a message be sent stating he and his crew will assist if necessary. They receive an emergency transmission from Praxis showing a Klingon worker consumed in flames. A second message comes from Brigadier General Kerla (Paul Rossilli) that acknowledges the explosion (he calls it "an incident") and that they do not require assistance from the Federation. He also commands them to stay out of the Neutral Zone. When one of the crew asks if they should report the incident, Sulu replies "Are you kidding??"On Earth two months later, Captain James Kirk (William Shatner), Dr Leonard McCoy (DeForest Kelley) and Engineer Montgomery Scott (James Doohan) attend a top-level meeting of Starfleet. They are told that the Klingon Empire "has roughly 50 years of life" remaining. Charge of the meeting is turned over to the Federation's special envoy, Captain Spock (Leonard Nimoy). He tells the committee that the explosion of Praxis two months earlier has caused an environmental catastrophe on the Klingon homeworld of Q'ono'S (Kronos). Pollution of the planet's ozone layer has left Klingon civilization with only 50 Earth years of oxygen. The Klingon Empire, due to its enormous military budget, is unable to reverse the devastation and has turned to the Federation for assistance. However, as Spock notes, assistance cannot begin until a treaty...
