Season 1 Episode 22
Episode: "Symbiosis"
The Enterprise's mission to observe the flare activity of a star is interrupted by a distress call from a freighter in danger of destruction from a decaying orbit. Interference from the local star's radiation complicates the rescue operation resulting in the freighter's destruction however several of the passengers are at least rescued; them and their cargo. We learn that the cargo is in fact medicine, containing over 4-billion doses of a drug called felicium, manufactured by a race called the Brekkians. For generations a race on a neighbouring planet, the Ornarans have been struck down by a planet-wide plague. Having discovered long ago that felicium can address their symptoms, the Ornarans have maintained a long running trade agreement with the Brekkians for regular deliveries of the drug.
In this instance however, the destruction of the freighter has meant that the goods the Ornarans had offered in trade for the felicium was also destroyed. This shipment of felicium is now in dispute with respect to who actually owns it. Naturally the Ornarans' needs are real and immediate however the Brekkians whose entire planetary economy is motivated by the sale of this product aren't prepared to simply let the cargo go absent payment.
Langor: "The Ornarans provide us with the necessities of life and we provide them with the necessities of living; it is a fair exchange." - Stuck with me that one.
