Episode cast overview:
Dr. Rabal
Dr. Serova


The Enterprise investigates the medical transport Fleming's, disappearance perhaps hijacked for its valuable gel cargo in the Hacares corridor, a region uniquely dense in tetreon interference which complicates navigation. DaiMon Prak's large Ferengi ship, the prime suspect, is stranded. He denies having attacked first, but helps with the search in exchange for engineering repairs. Geordi tries to boost the sensors as a matter of rivalry with his former teacher, and gets Data to try to 'train' cat Spot, who is of course too smart to be manipulated. The Enterprise runs into an immobilizing field, then gets boarded by Hacarian sibling doctors Rabal and Serova, who claim warp fields have fatal effects for their planetary population. They admit to having immobilized ships by buoys to make the Federation sit up, a theory Data can't verify for sure. Serova hijacks the Fleming to prove her theory at the ultimate price.

Data leans down to feed Spot and as he does this, you can see his sleeve roll up revealing that the android makeup is limited largely to his hands as his wrist and upper arm aren't painted. For reference 16:51 during the episode. See more »


Lt. Commander Geordi La Forge: My sister didn't know a thing about animals, and she was able to train *her* cat. How complicated could it be?
Lt. Commander Data: What did she train her cat to do?
Lt. Commander Geordi La Forge: She had that cat jumping into her arm on command.
Lt. Commander Data: Interesting. Perhaps I could modify your sister's techniques to keep Spot from jumping on the console. Do you know how she was able to train her cat?
Lt. Commander Geordi La Forge: Well, as I recall, she walked around for two months with a piece of tuna in her blouse.

A terrible attempt at an anti-pollution episode
9 March 2014 | by (United States) – See all my reviews

This was a terrible episode. And it would foreshadow the mediocre direction of Brannon Braga produced Star Trek. This episode was meant to make people think about pollution. But it used the fictitious warp drive as the method and created a story line that says warp speed was damaging space. All that was achieved was the very clear idea that Braga looked at his viewers as if they were children. This episode felt very much like some light made for kids show with superheroes giving us sermons of how we should live our lives.

This show may have been a swing for the fences by Braga in terms of landing some sort of award like the Peabody. Whatever his goal, it failed miserably.

Near the end the cast all take turns delivering political points on protecting the environment of space from further damage and the scene plays like a cheesy public service message.

It is incredible that they did not have the actors go ahead and officially break the 4th wall and deliver a message to the viewers from Braga. And they may as well have done that since the scene was so obviously written to make Trek and the actors look politically correct and the lines seemed to come from the actors not the characters.

This was very close to being The Next Generation's worst episode and unfortunately all of Braga's Enterprise and 75% of Voyager was far worse.

Brannon Braga is to Star Trek as Joel Schumacher to Batman. Braga killed Trek just as Schumacher killed the 90's Bat-films. Both are two men with no talent or instinct for entertainment and should be kept away from it FOREVER!!
