Unfortunately, the U.S.S. Enterprise discovers that the residents of the Darwin Station are suffering from the same mysterious affliction. Picard is asked to evacuate the children of the station, who have been engineered to become super-specimens through genetic research. Although the children have been kept in isolation and show no signs of infection, a cautious Picard allows Pulaski to examine just one child until the nature of the virulent disease can be determined.

To further eliminate any danger to the crew, Data and Pulaski board a shuttlecraft and have the boy beamed to that vessel so that he can be evaluated in a safe environment. But moments after Pulaski begins to examine the boy, she is stricken by the mysterious disease, which immediately begins working its rapid aging process on her.

In a desperate attempt to save Pulaski's life, Picard orders the crew to modify the transporter unit so that it can filter out any changes in the doctor by using a sample cell of Pulaski's DNA taken before her exposure to the infection. A short time later, with Picard at the transporter controls, Pulaski is safely beamed back aboard the Enterprise and restored to her normal age.

In celebration of Star Trek's 40th Aniversary, several conventions were held in its honor. Diana Muldaur hadn't done a Star Trek convention in 10 years. She participated in one in Las Vegas on Sept/15/2006, along with several other Star Trek veterans.

Diana Muldaur often plays physician roles. Her most noted ones in Trek lore were, respectively: Dr. Ann Mullhall (original series episode: "Return to Tomorrow") Dr. Miranda Jones (original series episode: "Is There In Truth No Beauty?") and Dr. Katherine Pulaski (season two of Star Trek: The Next Generation). Each having an open minded view of the Universe.
