STARGATE ATLANTIS SEASON ONE THIRTY EIGHT MINUTES EPISODE 104

Jumper One returns to the Stargate on final approach, after having suffered an attack from several remaining Wraith on their homeworld. Major Sheppard is in critical condition, having been bitten in the neck by a paralyzing insect that refuses to let go. After opening the gate to Atlantis, Jumper One begins to make its way through the event horizon, but becomes lodged mid-way via a damaged starboard drive pod that did not retract. Power is cut inside the ship, and it is imminently clear that the team has 38 minutes to live before the gate automatically shuts down.
Once minimal power is restored people begin to move about within the jumper. Ford, who is retrieved from the front compartment via his un-dematerialized arm, reports back to base and gives Weir information concerning their new problem (including the fact that two officers, Malcolm and Stackhouse, are now dematerialized within the gate itself). He then gives a run-down of recent events:

Jumper One returned to the Wraith homeworld to gain reconnaissance on the species, but when they reached the surface they found the colony to be gone. In its place was an enormous crater, which was not created by an explosion. It is soon surmised that the colony was actually a hive ship that had existed there for so long trees and forest literally grew on top of it. The ship is supposedly now off culling planets and restoring their species to power.
Apparently not all Wraith abandoned the planet, as several warriors chased the unit back to the Jumper. Sheppard, however, became lodged in an enormous web where the giant insect bit him and began to disable his immune system. Even a single Wraith warrior was dissuaded from killing him after seeing what had already begun to sap away his life.It was not long before everyone was back aboard the Jumper, and in a hasty retreat the craft's starboard drive pod was damaged by the Wraith.

Sheppard eventually regains consciousness and realizes that the team has not returned to Atlantis. McKay is busy taking readings of the ship. Back on Earth, an Apollo-13-style team has been assembled to try and analyze the problem from their end. Soon their best recommendation is clear: close the jumper's partition hatch and hope that atmosphere is maintained long enough to send a second jumper and tow them back when the gate finally disconnects, splitting the ship in two. McKay finally manages to close the partition, leaving everyone in the dark. Sheppard is beginning to lose feeling in his arms and legs, as well as patience with Rodney's mouth. Teyla tries to make John comfortable with a makeshift pillow as his condition worsens. Back at Atlantis, Dr. Zelenka and his team continue to work with a Jumper's computer pathways in the hopes of triggering (by accident) the appropriate command to close the drive pods.
Dr. Kavanaugh of the research team is only able to come up with more disturbing problems. If McKay continues to mess with the command pathways it is possible the drive pods could explode and send the end trails flaming back to Atlantis base. Weir is forced to point out, on more than one occasion, that she will not tolerate his attitude of self focus and preservation. Meanwhile, Dr. Zelenka has managed to isolate the drive pod control pathways, the data of which is transmitted to McKay, improving their odds of finding the correct switch from one in a million to one in a thousand.
