The Zephyr remains crash-landed on a frozen asteroid. A team is sent out to collect Toxin B-3, a potent bio-weapon that they've found here (to their surprise, since it was supposed to be found on another asteroid entirely), while Gossard and others remain at the ship to try to get the communications system working to send an SOS... and to protect the ship from Firefries, fire-breathing bugs that the Roughnecks accidentally brought to the asteroid as eggs. The collection team fights Leeches, aggressive amorphous blobs, inside a cave; in the aftermath of the battle they discover that the Leeches are the source of the Toxin B-3. But while collecting them the team finds itself at the mercy of a hurricane-force wind coming from inside the cave. The wind blows Carmen away, and the team fears for her life. The episode climaxes in a massive battle with the Firefries around the ship. When it's over, Gossard is able to send an SOS, and Carmen returns. It looks like help is on the way. (from pazs
