Gannet was a Human news reporter and Starfleet Intelligence operative who lived on the planet Earth in the mid-2150s.
Gannet had been romantically involved with Travis Mayweather prior to the launch of Enterprise NX-01. In an attempt to keep Mayweather from accepting a position aboard Enterprise, Gannet claimed that space exploration was the "last vestige of colonial impulse". Eventually, she and Mayweather made a mutual decision to end their relationship.
The crew of Enterprise later discovered that Gannet had reconfigured her universal translator at the conference on Earth to record messages from all the other translators and had been spying on the delegates there. Ensign Hoshi Sato claimed that Gannet had accidentally triggered an identification protocol in the network, which Sato had tracked back to the source. Most of the Starfleet officers suspected that Gannet was a member of the xenophobic organization Terra Prime. However, Ensign Mayweather believed that Gannet may have simply been doing undercover research for a news report.
In Enterprise's brig, Gannet requested to speak with Travis Mayweather. When the ensign arrived, she complained that she had not yet spoken to her lawyer. She also revealed that she was actually working for Starfleet Intelligence, not Terra Prime. Mayweather found her story hard to accept, however. He believed that Gannet would be able to quickly arrange her own release if she were employed by Starfleet Intelligence. In an attempt to explain why she had not already done so, Gannet replied that she was aware that a Terra Prime agent could possibly be operating on board Enterprise. Her own identity would be compromised if she were to attempt to contact the head of her division.
Shortly thereafter, Paxton was arrested and the Terra Prime spy aboard Enterprise, Ensign Masaro, committed suicide. Gannet was released from imprisonment and learned that peace conferences were continuing on Earth. She believed that, due to the work of Mayweather and others, the Coalition of Planets would eventually be formed. Mayweather agreed with her that, like him, Gannet had just been doing her job. She suggested that she and Mayweather should learn to "get along" like the Vulcans and Andorians, two members of the potential Coalition of Planets who were renowned for their discordant relationship. Mayweather commented that he and Gannet had much to discuss and accompanied her back to Earth in a shuttlepod. (ENT: "Terra Prime")
