The enterprise has been dispatched to the Hekaras Corridor; a narrow corridor through an otherwise impassable area of space, to investigate the disappearance of a medical transport ship. Suspicion falls on a Ferengi vessel that had been seen in the area. The Enterprise finds the Ferengis but they appear to be dead in space. After a brief confrontation it emerges that they had activated a mine which had been disguised as a navigation buoy. The Enterprise investigates further and triggers such a mine soon after is boarded by two aliens. They are a brother and sister who claim that ship's warp engines are causing dangerous effects near their home world that will ultimately cause a spatial rift that could destroy the planet. Picard promises to forward their research to the Federation but that isn't enough for the sister
she decides to prove her theory in a suicide mission that deliberately causes a warp core breach in her ship. The resulting explosion does indeed cause a rift and the medical ship is caught inside it; the crew of the Enterprise will have to find a way to rescue them which doesn't involve using the warp engines within the rift. In an early side story Geordi has difficulty while looking after Data's cat; Data tries to train it but his efforts have little effect; we also have another side plot involving Geordi trying to increase the engine efficiency as part of a rivalry with an engineer on another ship.
This was a fairly disappointing episode; it starts with a rather unnecessary plot involving Data's cat that, while amusing at times, didn't really go anywhere. Likewise the subplot about Geordi's rivalry with a fellow engineer didn't add anything to the story. These aren't the main problems with the episode though; that is the overly preachy nature of the main plot. We are clearly meant to see a parallel with the problems caused by warp travel and pollution. We also have the unlike way that the female alien causes a rift to prove her point in a way that will probably affect her planet far more than the passing warp-powered ship. The resolution where a speed limit of Warp Five is imposed on the Federation seems to be something that could limit future stories although I don't recall this limit being applied in 'Voyager' and 'Deep Space Nine'. Overall a rather disappointing episode where the subplots go nowhere and the main story is overly preachy.
