A local scientist, Flint Lockwood (Bill Hader), has always been a failure, but when his town is stuck eating gross sardines, Flint wants to help the town so that they don't have to eat sardines anymore. So he invents a machine called The FLDSMDFR, (Flint Lockwood Diatomic Super Mutating Dynamic Food Replicator), a machine that can turn water into food. And he sends it up into the atmosphere and makes food rain from the sky. But suddenly, things get out of hand when The FLDSMDFR creates dangerous food storms. It's up to Flint to stop The FLDSMDFR before it turns the world into a monstrous Foodtopia.
