在这部超人和鼹鼠人剧情/动作/科幻/家庭/奇幻片中,记者克拉克·肯特（超人）和露易丝·莱恩抵达小镇西尔斯比，采访并见证世界上最深的油井的钻探。然而，这种钻头已经穿透了一群毛茸茸的小矮人鼹鼠人的地下家园，这些鼹鼠人会在夜间浮出地面四处张望。他们在黑暗中发光的样子吓坏了市民，鼹鼠人组成了一个暴徒，由邪恶的卢克本森领导。只有超人才有机会阻止这场悲剧。
Reporters Clark Kent and Lois Lane arrive in the small town of Silsby to witness the drilling of the world's deepest oil well. The drill, however, has penetrated the underground home of a race of small, furry people who then come to the surface at night to look around. The fact that they glow in the dark scares the townfolk, who form a mob, led by the vicious Luke Benson, intent on killing the strange people. Only Superman has a chance to prevent this tragedy.
