For descendants of these colonists, this spaceship is a homeland mother. All of themworking to offer a best future to their children. While the major part of this generation is satisfied, some have become impatient and nervous.
A "Viper" jet squadron leaded by David Ryder transporting the Professor Thomas Gruder is attacked by pirates, while on board the "Southern Sun", Captain Elijah Kalgan, leader of a rebellion puts explosives. Interceptors Viper are in phase of landing when resound explosions on board the gigantic vessel. David Ryder teleports just in time to avoid death, but unfortunately, it will not be the same for the Professor. Kalgan as chief of a unprecedent mutiny, wants to perplex the vessel to Corona Borialus, a pirate territory.

Whole is well that finishes well, the mutiny is stopped, delinquents punish, and Lea and David are going to marry. But is Kalgan realy dead ?
A low budget movie that uses numerous footages from the motion picture "Battlestar Galactica". Thus the spaceship called "Southern Sun" is just the "Galactica" from which leaves "Viper" interceptors (scriptwriter did not even change their name) and are attacked by pirates that are true Cylons ! Special effects might not have costed too much to producers !
