FlashForward is an American television series, adapted for TV by Brannon Braga and David S. Goyer, which premiered on ABC on September 24, 2009. It is loosely based on the 1999 novel Flashforward by Canadian science fiction writer Robert J. Sawyer.

The series revolves around the lives of several people as a mysterious event causes nearly everyone on the planet to simultaneously lose consciousness for two minutes and seventeen seconds on October 6, 2009. During this "blackout," people see what appear to be visions of their lives on April 29, 2010, a global "flashforward."

The show is currently in its first season which will end on May 27, 2010, outside the traditional May sweeps period.

A mysterious event causes nearly everyone on the planet to simultaneously lose consciousness for 2 minutes and 17 seconds, during which people see what appear to be visions of their lives approximately six months in the future—a global “flashforward”. A team of Los Angeles FBI agents, led by Stanford Wedeck (Vance) and spearheaded by Mark Benford (Fiennes) and his partner Demetri Noh (Cho), begin the process of determining what happened, why, and whether it will happen again. Benford contributes a unique perspective on the investigation; in his flashforward, he saw the results of six months of investigation that he had done on the flashforward event, and he and his team use those clues to recreate the investigation.

The team investigates a number of events related to the flashforward, including "Suspect Zero", who did not lose consciousness during the event, the sinister "D. Gibbons", and a similar mass loss of consciousness in Somalia in 1991. Meanwhile, personal revelations contained within the flashforwards occupy the personal lives of the principal characters. Mark Benford sees his alcoholism relapsing, his wife sees herself with another man, Demetri Noh sees nothing which could mean he will not be alive to see the day of events everyone else has witnessed. Other characters grapple with similarly unexpected or surprising revelations in their flashforwards.
