It covers his entire campaign in 2012 from start to finish, and it's an interesting insight into what that process is like. The most poignant moment of the whole documentary is, while sitting in a hotel room surrounded by his family and campaign team, when Romney realizes he's lost the election - you can see it in his eyes. It was genuine surprise, shock and sadness all at once.
I found the whole thing fascinating for that one moment alone. Like, losing the presidential election, I can't imagine what that would feel like. After all that money spent, all those rallies and speeches, for nothing. Your name will go down in the history books as "the dude who lost". That's gotta sting.
