Aspiring inventor Flint Lockwood is the socially awkward genius behind some of the most bizarre contraptions ever conceived. But even though all of his inventions, from spray-on shoes to a monkey thought translator, have been spectacular failures that caused trouble in his small town, Flint is determined to create something that will make people happy. When Flint's latest machine, designed to turn water into food, accidentally destroys the town square and rockets up into the clouds, he thinks his inventing career is over. Until something amazing happens -- cheeseburgers start raining from the sky. His machine actually works! The food weather is an instant success, and Flint forges a fast friendship with Sam Sparks, the weathergirl who comes to town to cover what she calls "the greatest weather phenomenon in history." But when people greedily ask for more and more food, the machine starts behaving erratically, unleashing spaghetti tornadoes and giant meatballs. With the town about to be buried beneath mountains of marshmallows and waves of watermelons, it's up to Flint and Sam to use their combined expertise to shut down the machine and put everything right.
