A tale of boxing, time travel, multiverses, quantum physics, love, loss, pain, redemption, and how you may think you are through with the past, but the past is never through with you.

On June 17, 1970, Jerry Quarry, the most popular fighter on the planet, knocked out unbeaten Mac Foster in Madison Square Garden. Before the main event, 15,951 fans and more than a dozen champions celebrated Jack Dempsey's 75th birthday. But other things happened that night.

In the not-too-distant future, scientific breakthroughs allow a flamboyant boxing promoter to bring together "genetic holograms" of the sixteen greatest heavyweights in history, fighting on what was the best day of their careers to crown the Heavyweight Champion of the Multiverse. There's just one glitch. Jack Dempsey can't be found, and a former Golden Gloves fighter must rescue the tournament by revisiting events from the pivotal night of his life, a night that has haunted him for decades.
