Ennio is the product of a genius mother and a genetic lab and was set for an extraordinary life. But by the age of twelve, he ends up alone on the streets of Metro, the biggest city in the world. Crime is the only way to survive and his way to the top. A decade later, he is known as the Falcon, the deadliest hitman in the world. But betrayal makes him lose his whole world, even his wife and unborn son. Chewed up and spit out as a heroine junky, he is back on the streets where his journey once began. A greedy friend sees potential, gets him back on his feet, and trains him into a master thief. When a mission to steal crystals in a remote research center goes sideways, he ends up on the research table himself. Great is their surprise to see that this ordinary thief is now the biggest treasure inside the center.

The key to the survival of the Earth is in his blood, but Ennio is not willing to give himself up without a fight. His super muscular body and indestructible ego make him the toughest nut to crack. Leaving a trail of wreckage behind him every time he is challenged makes him destined to be terminated soon. So they need another way to get him to his knees-time to get out the biggest weapon of all...love.

The research center, The Hive, is set up like a colony. There are workers, soldiers, and breeders. Once a specific caste claims a person, there is no way out.

Ennio is a prisoner and research guinea pig in the lowest castes.

He is given a chaperone to keep him entertained and out of trouble. Nazzarine, a young "worker" girl, is appointed for the job. Much against her will, but without any say in the matter, she is placed on living with him. What starts as a horrible experience slowly becomes a symbiotic relationship and will later bloom into love.

Ennio struggles in his new environment, where he is constantly forced to his knees.

When he is offered the opportunity to become a soldier, he grabs it in the hope that he will be able to escape the Hive that way. However, his superior, Tabris, thinks he is most unworthy to fill a spot in the Royal troops and is doing everything in his power to block Ennio. Things escalate quickly, and when Ennio has Tabris in his power, ready to break his neck, rescue comes from a very unexpected corner. The cards get shuffled, and the game is on....
