Apollo and Starbuck come across a vessel they think may have come from Earth and take it aboard the Galactica. On board are two adults and four children in a state of suspended animation. Adama disagrees with the Council of Twelve about opening the sleeping chambers, for that may mean endangering the humans within. When the adult male, Michael, wakes up, he finds it difficult to breath the air on board the Galactica. Apollo, Starbuck and Cassiopea decide to escort the Lunar Shuttle Avion to its destination, hoping to find out if the travelers home, Terra, may be related to the planet Earth.
