In an effort to save a couple crewmen from a fellow Starfleet ship that has become involved in a civil war on a planet that turns out to be the birthplace of Tasha Yar. The civil war has led to great violence, including the slaughter of trespassers. One group, the Alliance,has held the other at bay. It turns out that Tasha Yar's sister is an insurgent rebel. She is brought on board the Enterprise and joins them in rescue efforts to save the two men trapped below the planet. The leaders of the alliance give an ultimatum and the Enterprise must act. Ishara Yar masterfully gains the trust of the crew and is given great latitude in the rescue operation. During this time she is very critical of her sister. Data informs her of Tasha's great character and bravery. It seems the war on the planet excludes any sisterly affection and Ishara felt that Tasha took off rather than fight. I really believe that the show went for more believable encounters and actions. This is one of those that shows us that the writers were really gaining steam.
