Trevor Anderson (Brendan Fraser) is a professor of science and clings to a theory that there is a center of the earth man can travel to. Ever since his brother was lost trying to prove this theory, Trevor has fantasized about finding some sort of sign to prove he was right. But what he doesn't expect is to have his brothers son Sean Anderson (Josh Hutcherson), dropped in his lap to spend time with now that his father is gone. He figures Sean might be in the way of his determination, but he also looks at it as a way to give his nephew a piece of his father back.
On a whim, the two travel to Iceland and meet Hannah (Anita Briem). Hannah too has lost her father to the believe of this underground world. When the trio finds evidence of her father's research, the three set out to find more clues. But a lightning storm traps them inside a cave with the only way out going down. Once below the surface of the earth, they must find their way back out before either becoming dinner for some large plants and creatures or being evaporated in the constant exchange of molten rock.
