When Lucy's parents announce that the family needs to move, Lucy is devastated that she will no longer live near her best friend.  Determined to use her love of Science to find a solution to this frightening change, Lucy turns to her magic lab coat. With her coat and a little imagination, Lucy travels into the earth where she talks to a frightened Magma in the moments before he explodes into a volcano.  She journeys to the bottom of the sea where she discusses evolution with an anglerfish and, finally, out into space where she discovers that humans exist only because stars die.  As Lucy peers into the vast unknown, she is forced to grapple with the necessity of change and the importance of Science even when it doesn't have all the answers.
