This show lasted only one year (1995-96) and I am not sure I saw every episode. Bruce Greenwood plays a photo-documentary maker whose whole existence is erased in the time it takes to use a restroom. It appears everyone in his life has been persuaded to lie to him. He comes to believe that his circumstances relate somehow to a photo he took of four men being hanged in South American.
It harkens to a lot of other movies and shows like CORONET BLUE, THE MANCHURIAN CANDIDATE, etc. It was expected to be a huge hit, got great reviews, but disappeared. I love this sort of show, but they often seem to self-destruct. Maybe in 1996 we weren't ready for story arcs quite yet. Or maybe this should have been a movie rather than a TV show since it hung so much on a conceit.
