Whilst on a mission to observe the development of protostars in the Volterra Nebula, Captain Picard is visited by his old Academy archaeology mentor, Professor Galen, who invites Picard to join him on a long expedition he claims to be of great historical importance. Upon being refused again in favour of fleet duty, Galen goes alone, but his shuttle is captured by Eurydians, who sell his vital findings, which Data, La Forge and Crusher help decipher, revealing an incredible DNA sequence, common to at least nineteen independent sentient life forms. As it turns out, it was sold to the Klingons and Cardassians too, who arrive simultaneously at the planet, from where they suspect the common source, which included a hidden 'program', originated. Yet this setting holds further surprises from still other races. Written by KGF Vissers

Did You Know?


Jonathan Frakes was disappointed that he couldn't direct any outdoor scenes. They didn't have the money for it because it was being spent on Star Trek: Deep Space Nine (1993). The set designer Richard D. James said it wouldn't have made a difference anyway, because the crew couldn't find a salt flat without vegetation, as the episode demanded. See more »

Doctor Beverly Crusher: [referring to Professor Galen] If it hadn't been for you, his dream to solve that puzzle would never have been realized. You left him a wonderful legacy.
Captain Jean-Luc Picard: Yes, but it would have been a more fitting legacy if the message had not fallen on such deaf ears.
Doctor Beverly Crusher: Hm... You never know.

We're not so different
2 August 2017 | by (United States) – See all my reviews

With a title like 'The Chase', this episode fuels certain expectations

  • which end up being defied because this is neither cat-n-mouse nor a
race. Which is integral to why this is so good. What starts out as Picard reflecting on those career paths not taken switches gears into something more like a mystery thriller. The key to this is the execution; it's a smooth transition (Frakes at the helm) and the endpoint on this journey brings the major raves together (except for Vulcans) for a curious revelation. But there was real though put into this and the effort to address the differences and similarities in Star Trek makeup effects is evident.

It's a great episode.
