The SG-1 team is transported to a planet of opposites, the home of a sole survivor of an aquatic race. Teal’c, O’Neill and Carter return to Earth shell-shocked and disturbed. Can the team recover to find Daniel and attempt a rescue? [Edit]

The SG-1 team returns from the planet Oannes in a panic — and without Dr. Daniel Jackson, who was last seen being consumed by a column of flames.

As his comrades mourn him on Earth, however, Daniel is held captive by an amphibious, humanoid creature known as Nem, who is seeking information about his partner, Omoroca, who lived on Earth 4,000 years ago.

Daniel struggles to recall his Babylonian history and agrees to have his brain read by Nem's advanced (and possibly deadly) technology. Daniel discovers common ground with Nem — both have lost their true loves to the murderous Goa'uld — and the key to his freedom.

Back on Earth, the SG-1 team struggles with the strange feeling that Daniel isn't really dead. The team members use hypnosis to revisit the events leading up to Daniel's disappearance...and their discoveries lead them to gear up for a return to Oannes.... [Edit]
