A rousing page-turner about a boxer on the downside of his career who helps a troubled but talented contender make his way to the top.

Aging and not as quick as he used to be, Amos "Scrap Iron" Fletcher has finally arrived in Las Vegas, capital city of boxing. His years of slugging it out as a sparring partner for heavyweight contenders are about to pay off. But after his first big-league fight ends in defeat-and when he's falsely accused of offering to sell secrets to his sparring partner's opponent-he heads back home to Trenton to figure out his next move.

It's there, at his uncle's boxing gym that he's reunited with TNT, another boxer down on his luck. TNT is a reckless but kindhearted kid who just happens to throw some of the toughest punches Amos has ever seen. TNT's hunger for vindication rekindles Amos's passion for the sport, and he agrees to take the neglected young fighter under his wing.

With a little help from boxing idol Sonny Liston, who's always in the back of his mind, Amos forms a training strategy for TNT and launches a daring gambit to reclaim his own reputation. So begins Amos and TNT's thrilling ascent-guided by Liston's defiant spirit-to the title fight that every boxer dreams about: the Heavyweight Championship of the World.
