The crew of the ‘Destiny’ find out that their water supply has been disappearing mysteriously. Col. Young posts soldiers to guard their supply, some of which they initially think had evaporated when they entered the star. However that theory is soon ruled out. Young asks Dr. Rush about the possibility of dialing Earth from their Stargate but the scientist replies that as ‘Destiny’ is very old it could only charge upto 40% of it’s actual capacity when it entered the star.
Meanwhile Eli is asked to spy on the rest of the crew to see if anyone is stealing the water. As tensions start to mount, the ship dials the gate of an icy cold planet which has potentially a large supply of drinking water in the form of solid ice. Lisa Park and two other scientists have worked on repairing two Ancient environmental suits and Young & Lt. Scot are given plasma cutters to cut off huge blocks of ice which can replenish some of their water supplies.
Spencer is caught hoarding two cans of water and several energy bars, which he protests that he took before they entered Destiny. However the rest of the crew know that he was holding out on them to satisfy his own needs before the others. Tamara Johansen meanwhile confronts an alien entity that resemble swarms of flies and which had followed Lt.Scot from the desert planet. These flies are the culprit, draining the water supply. Unfortunately Gorman provokes the swarm by firing at them and they retaliate by cutting his skin several times. After losing a lot of blood, he dies in the makeshift infirmary. Tamara lures the bugs into a barrel of water and they toss the barrel through the stargate into the ice planet.
Meanwhile Scot & Young have brought back a lot of water which will suffice for the time being. They almost lost Scot when he fell into a crevasse and it was with Col. Young’s help that he was able to pull himself back up again before the Destiny entered FTL again.
