The government of Chal requests, and is given, the Enterprise-A, and the Chal government gives the ship to Kirk, who proceeds to Chal. Drake, enlisting the aid of Captain Sulu, the Excelsior, and the rest of the former Enterprise senior officers, pursues Kirk, whom he charges with acting against the Federation. It is subsequently discovered that Chal was an experimental colony of Klingon/Romulan hybrids developed to survive a feared war with the Federation, resulting in a genetic structure that could retard the aging process. It is also discovered that Drake is a member of the same conspiracy as former Fleet Admiral Cartwright, and intends to sabotage the Federation-Klingon peace process. In the incident’s culminating battle, the Enterprise-A is destroyed (though its crew are all rescued by the Excelsior) and Drake is killed. Chal is saved for its people. Kirk returns to Earth.
