Leo Kane, a gifted orphan genetics genius from a humble background, invents groundbreaking Chimera genetic serum and plans a future with his wealthy fiancée Victoria. Betrayed ruthlessly by Victoria and arrogant heir Damien Cross, alongside Damien’s cold-blooded tycoon father Marcus, Leo’s research is stolen, false charges land him in jail, and he’s dragged to a secret underground lab for illegal human trials. Forced to endure an injection of savage beast serum, Leo is dumped into the ocean to die after the brutal experiment.
Against all odds, he merges with the serum and awakens unmatched beastly power, rapid regeneration and amplified intelligence. Silas, a disfigured former Cross scientist ruined by the family, rescues the broken Leo, teaches him to control his monstrous form, and reveals the bitter truth: Marcus murdered Leo’s father and stole his co-founding company shares decades ago.
