Gary Seven - Assignment: Earth

Assignment: Earth

The episode "Assignment: Earth" was a television pilot for a proposed series about Gary Seven, a human who lives on Earth but who works for the inhabitants of another planet. His mission was to prevent nuclear war on Earth by sabotaging a missile platform launched by the United States in 1968. Seven is encountered by the crew of the Starship Enterprise, who have been sent back in time by the United Federation of Planets to find out what actually had occurred on Earth in the late 1960s.

Seven's secretary was Miss Roberta Lincoln (portrayed by Teri Garr) and was originally unaware of Seven's origins, thinking she was working for a couple that was researching a new encyclopedia. Seven also had a constant companion in Isis, who at first appears to be an ordinary cat, but is shown to have great intelligence and in fact turns out to be able to alter its shape to become what appears to be a human female, which Miss Lincoln discovers during one scene as Isis changes shape into a human female and then back into a cat.
