The Cassiopeia brigade hires a young pilot. She is ordered to pilot the Cassiopeia 3 on their diplomatic mission across the galaxies. On the missions, she is confronted with various conflicts and the tragic past of the Cassiopeia 3 and its crew.
During the preparation for the final pilot exam at the Earth Academy for Intergalactic Relations, Trade and Travel, Earth has been taken hostage by an ally of the Farser, a hostile alien race and a superpower in the intergalactic relations. As a measure of defence the AIRTT orders the students to their defence posts. Sara Abigail, a young pilot who is supposed to take her final exam in one week, is ordered to serve aboard the spacecraft DS1406 as co-pilot to provide support in case of an escalation of the situation. The Cassiopeia Brigade has been notified and they have send the space ship Cassiopeia 3 and its crew to assist the AIRTT, but they will only arrive in two weeks. The crew of the DS1406 are going through standard procedures for a longer mission in a geostationary orbit around Earth, as the situation escalates and they are caught in the middle of the conflict. The crew is imprisoned by the enemy and send to a distant planet. The crew, with now knowledge of where they are, must survive on this hostile planet, contact Mission Control and somehow make it back to Earth. Will they make it back? Will Earth still exist?
