The Enterprise is transporting several diplomatic delegations to a conference on Babel regarding the future of the mineral-rich planet Coridan. Among the passengers are Spock's parents, Ambassador Sarek and Amanda. There is obviously a chill between father and son owing to Spock's choice of pursuing a career in Starfleet. Unknown to Spock or his mother is the fact that Sarek is seriously ill. There is also much tension among the delegations and a spy on board is transmitting coded messages to a ship that attacks the Enterprise. With Captain Kirk wounded in an earlier knife attack, Spock is in temporary command just as his father needs a transfusion that only he can provide. Written by garykmcd

User Reviews

Very good show with some great insights into Spock
7 December 2006 | by MartinHaferSee all my reviews

This is perhaps one of the best episodes for the Spock groupies out there. In this one, his personality is allowed to show through much more than usual and these insights are gained by watching Spock with his parents, Jane Wyatt and Mark Lenard. We learn that he had a teddy bear (of sorts) as a child and we also learn of Spock's anguish growing up as a "half-breed". On top of all this great family interaction, it was great to finally see multiple species other than humans in an episode, as the ship was ferrying ambassadors to a peace conference.

Pluses for the episode apart from the insights into Spock were much, much better than usual dialog, an exciting and multi-layered plot and plenty of action despite the episode taking place entirely on the Enterprise. All in all, one of the better episodes and one nearly meriting a score of 9.
