Watch this video of a Paralympian's journey to the Games. It's worth the minute you'll spend on it.
The concept in and of itself is incredible. Starring Canadian Paralympian Alister McQueen, the ad shows how a Paralympian truly exemplifies the word "unstoppable." Though it is not McQueen's story, it shows everything a Paralympian can go through on the way to the Games, and how that struggle is ever-present through training.
Knowing the backstory behind the ad makes it even more incredible. It was done in one, continuous take, with no special effects. McQueen was actually running through every wheelchair, crashed car and smoke that was in his way.
