John Doe is an American science fiction drama television series that aired on Fox during the 2002–2003 TV season.

In the opening scene of the series' pilot episode, a mysterious man wakes up on an island off the coast of Seattle, Washington, naked, with absolutely no memory of who he is or how he got there. However, apart from the details of his own past, "John Doe", as he comes to call himself, seems to have access to the sum total of all human knowledge: he knows how many dimples are on a golf ball, the population of Morocco, and other such obscure (and not-so-obscure) facts. He also has expert knowledge on everything from the stock market to computers. Over the course of the series John attempts to find clues about his past by using his unusual ability while also helping to solve crimes with the Seattle police department. In the process it becomes clear that an international conspiracy known as the Phoenix Organization is watching John's every move.

Who is John Doe?

Due to the series' cancellation, the final episode ended with an unresolved cliffhanger, revealing that Digger, John's close friend, was in fact the true leader of the Phoenix Organization. In an interview with Entertainment Weekly, series creators Brandon Camp and Mike Thompson revealed what would have happened and John Doe's true identity.

Make that someone who looked like John's friend. The villain unmasked in the finale was actually just a Phoenix member with some fancy facial reconstruction. Turns out, the Phoenix believed Doe was the Messiah and its members were actually protecting Doe from a second group, which wanted him dead. The truth: Doe was injured in a boating accident. That mark on his chest? A scar left by a piece of shrapnel from the explosion. His Überbrain? A by-product of transcending his body during a near-death experience, traveling to a spiritual plane where all the universe's questions are answered.
