Matt and Jeff, two brothers from North Carolina, had a dream that they would one day become professional wrestlers. They trained themselves, they formed a backyard wrestling league, they worked indie shows for no money, and they loved every minute of it. When they were finally handed contracts, they didn't bother reading - they just signed the lines knowing that their lives would make a huge change for the better.

Leap of Faith takes us on Matt and Jeff Hardy's journey toward stardom.

The story begins in their home of Cameron, NC, where we learn about their early days. Their dream of being wrestlers began in the late '80s, and they quickly began working toward that goal. Matt learned to sew so that they could have costumes. They videotaped their goofy promos, some of which we get to see on the DVD. They also set up a wrestling league in their own yard.

In addition to background, we also learn about the Hardyz' personalities - they're not too far from their wrestling gimmicks. Through interviews with them, their father, and fellow wrestlers, we learn that Matt is the focused, responsible one, while Jeff really is the eccentric, crazy one. They even show footage of Jeff building a volcano in his backyard so that he can jump over the flames with his dirtbike.
