Chariot of the Sun - S1.E19

The gang find a mysterious ship emitting dangerous energy on an uninhabited planet. While Harrison and Seattle look for the owners the others break into the ship, much to Stacey's concern. Gus insists on using the ship to return to nearby Earth, unaware that it's actually a Tlak'khan trap - the ship takes them to Ga'Harn, the Tlak'khan homeworld. Da'kyll captures them all and holds them back from the Nax'kan Council by claiming Warrior Right of Capture. Hah'lak sends his own operative, Gal'korn, to free first Gus and then the rest of the SG team and they see through the deception. They get their vehicles and weapons and get to the nearest Stargate to make their escape.
