Troi’s shuttle crashes on a desolate planet and the Enterprise is off to save her. Worf gets promoted to Chief of Security. Hint, Hint.

Yeah, this is the famous episode when Tasha Yar gets killed. This apparently was not very popular with fans back in 1988. This is the first appearance of Armus, who will be referenced many many times a few decades later in Lower Decks.

I summarize the plot and point out and explain all the references so you don’t have to.
