icard and the Enterprise respond to a distress call from its sister ship the USS Yamato. It has been facing a number of serious technical glitches and they lost 18 crew members when the computer turned off the force field on an open shuttle bay. Before the Enterprise can assist however, the Yamato is destroyed with all lives lost. The explosion is apparently the result of a failure in their matter/anti-matter pods but Picard suspects it may have something to do with a relic the Yamato's captain obtained on an archaeological dig on a nearby planet. They are in the Neutral Zone and are being shadowed by a Romulan ship but Picard, an amateur archaeologist, leads an away team to the planet to see what is causing the problem. When the Enterprise's shields inexplicably activate, they have no means to beam the away team back on board.
