In a world terrorized by the madness of science and the unrestrained experimentation of humanity, a giant monster emerges from the shadows after a tragic accident. Following a military experiment gone horribly wrong to enhance a soldier's physical capabilities, humanity faces catastrophic consequences. Colonel Glenn Manning, transformed into a 60-foot colossus due to an enhanced serum, becomes an uncontrollable beast that unleashes panic in his wake.
Meanwhile, his brave and determined sister, Carol, desperately searches for a way to rescue her brother, intent on finding a cure before he causes further destruction. The struggle intensifies as Glenn, trapped in his monstrous form, becomes both a threat and a being desperately seeking his lost humanity. The city turns into a battleground between the military forces trying to stop him at all costs and the fraternal bond that Carol is trying to restore.
As chaos unfolds and cities lie devastated in the giant's wake, it falls to Carol to make the world understand that within this chain of destruction lies a heart that still beats. In this story of love, fear, and redemption, we question how much a sister is willing to risk to save her family, even when it has grown to unimaginable scales.
