When Seven of Nine locates a massive communications array, Voyager
tries to use it to communicate with the Alpha quadrant. When their attempt fails, they realize they may be able to successfully send a holographic message, using the Doctor’s program.
However, the Federation ship in the Alpha quadrant the Doctor is sent to, is under attack by the Romulans and the crew is dead. The Doctor is determined to fight off the attackers, but the ship’s holographic Doctor isn’t as brave as Voyager’s
Doctor in this matter.
