Her need to solve a four-billion-year-old genetic mystery for an unlimited power source brought her to planet Loren III, along with the USS Enterprise-D and the Klingon vessel IKS Maht-H’a. After an agreement was reached between the three vessels she beamed over to the Enterprise to discuss the puzzle. During the meeting she attempted to deny having a piece of the puzzle on her ship, and was in fact examining the planet for colonization. Captain Jean-Luc Picard called her bluff and discovered that all three races had a piece of the puzzle. Agreeing to cooperate for scientific purposes, Ocett handed over her piece of the puzzle.
Once the Enterprise crew discovered where the last piece was, the Rahm-Izad system, Ocett betrayed the other two by attacking them. The Enterprise crew, expecting betrayal had given her a fake system and had prepared for the attack. They then proceeded to the Vilmoran system, which was the actual location of the final piece.
Finally, figuring out that she had been tricked Ocett turned around and intercepted the Enterprise. She then beamed down to Vilmor II with a guard and attempted to take the final sample. However, her plan was stopped when a group of Romulans, that had shadowed the three races’ efforts, appeared. Ocett then threatened to destroy the rock face instead of allowing the Romulans to get it. This led to a standoff between the Cardassians, Romulans, and the Klingon captain Nu’Daq. While this was going on Picard and his chief medical officer, Beverley Crusher, were secretly finishing the puzzle.
To Ocett’s surprise, the puzzle said that all races had been created from one race. She was greatly disgusted at being related to a Klingon, and disappointed that there hadn’t been what she was looking for.
