ST:TNG:15 - "Angel One" (Stardate: 41636.9) - this is the 15th episode produced but was the 14th episode to air on TV. The theme of this episode is that change is inevitable - this is pointed out in the matriarchal society of Angel One (a non-Federation world) that the Enterprise crew travel to. While Riker leads an away team to negotiate the return of Federation survivors (all male), Picard and crew on the Enterprise mysteriously contract a virus that plagues the ship. It's up to Dr. Crusher to figure out what's going on and when Picard falls prey to the virus, Geordi LaForge is put in command of the Enterprise! An unremarkable episode but has its highlights and humor.
