Travelers is a science fiction television series created by Brad Wright, starring Eric McCormack, Mackenzie Porter, Jared Abrahamson, Nesta Cooper, Reilly Dolman, and Patrick Gilmore.

These operatives, known as "travelers", have their consciousnesses sent back in time and transferred into the "host" body of present-day individuals who are about to die, minimizing unexpected impact on the future.
