A plutonium test in the Nevada desert leaves Lt. Col. Glenn Manning still breathing, then still growing. His cells stop listening to his body. Inch by inch he becomes sixty feet of furious, half-naked giant, dragging his sanity behind him. Bert I. Gordon, the man whose initials read B.I.G., wires up rear projection and oversized props until Las Vegas itself becomes a dollhouse to be smashed. Atomic-age anxiety blown up to drive-in proportions. Pure American grindhouse, body horror disguised as creature feature.
