Imagine this happening to you: You're riding a train, past houses, old buildings and bridges, in a city you don't recognize. You don't know who you are, and you have no identification.
That's exactly what happened in July 2002 to a man who later discovered his name is Doug Bruce.
Bruce checked himself into a hospital, where the nurses wrote "Unknown White Male" on his chart. Eventually, doctors diagnosed in Bruce a rare form of amnesia -- he had completely lost his memory.
In time, Doug Bruce learned he was in New York, but that he'd grown up in Africa and England, and he had friends dotted around the world.
One of them was British filmmaker Rupert Murray, someone he'd known for 20 years, but now could not recall in the slightest. Murray asked Bruce if he could make a film about what was happening.
The result is a new documentary by Murray, "Unkown White Male," which opens in the Twin Cities this weekend.
Murray told Minnesota Public Radio's Euan Kerr it took a long time to come to terms with his friend's condition.
