 Enterprise discovers a class 9 gas giant and Archer orders to take a look. A probe picks up something unusual: a ship is slowly sinking into the atmosphere and at its present rate of descent the pressure will crush the ship in about an hour. Reed and T Pol are sent to take a shuttle pod and see what they can do for the crew of the ship. At the last moment Hoshi Sato asks to join the mission. She tells Archer she finally found her  space legs . After entering the alien ship, Sato quickly sees it is Klingon. The crew seems to be unconscious.
