In this episode, en rout to the space station K-7 The Enterprise receives a priority one distress call from the station and rushes to its supposed recue. When arriving at K-7, Captain Kirk finds out that a Federation big-wig sent out the distress call to simply get a Federation ship in the area to protect a shipment of quadotriticale. This quadotriticale is apparently the only thing that will grow on a planet that both the Federation and the Klingon Empire is positioning for and is therefore of high importance. Naturally put off by the undermining use of the priority one distress call simply to get the Enterprise to babysit some bio-enhanced grain, Kirk is nonetheless forced by Federation officials to keep an eye on the shipment of quadotriticale. But the job ends up being of far more urgency and importance when a Klingon warship shows up.
"The Trouble With Tribbles" is one of the best episodes of the original Star Trek TV series and is also probably the most well known Star Trek episodes by non-Trekkers. It shows the Enterprise crew in a serious but also lighthearted manner - having fun but also having an important job to do. Also, the cast is at their Star Trek-defining bests with Scotty having an extended role in this episode - something that is not always seen throughout the Star Trek TV series and it is always nice to see more of Scotty! The best aspect of this episode is that most of the storyline centers on diplomatic issues that face the Federation, which is interesting and something that I particularly get into. And, of course, there are the many furry little tribbles that make this episode famous - and fun.
