The trailer shows Wade explaining how he felt watching
San Antonio's Manu Ginobili stepping to the free-throw line with 28 seconds left in last year's NBA Finals Game 6 with the
Spurs leading by four points.
"It sucks," Wade says. "And then, he misses one."
"D. Wade's Journey to 3" reportedly shows Wade discussing his injuries last season, and includes some behind-the-scenes footage of the guard's workouts. There's even a sparring session with LeBron James before Game 1 of the finals.
"I think it's going to give people a different perspective on what it all meant to me," Wade told the Associated Press.
Footage of the team's post-game celebration and the victory parade also is included in the full-length video.
