Peacekeepers

Exploring a deserted alien spaceship, Lt. Commander Data and Lt. Geordi LaForge suddenly find themselves transported light-years away - into the middle of a deadly conflict!
While Captain Picard and the crew of the Enterprise search feverishly for the missing crewmen, Data and LaForge discover they are in a station almost identical to the one they were exploring, high in orbit around an Earth-type world. Years before, the occupants of that planet accidentally stumbled onto the ship and its advanced technology - and since then have used its weapons to keep the nations on that planet below disarmed, and at peace.
Now their own arrival has precipitated a crisis on the station. Somehow, Data and LaForge must find a way to restore trust between the planet below and the station's guardians up above - before a final, destructive war breaks out!
