On the small island of Swallow Falls, there lives a young man named Flint Lockwood (voiced by Bill Hader). Since childhood, he has been full of ideas and passionate about all kinds of scientific inventions, such as shoeless shoes, self-walking televisions, flying cars, and monkey language translators. Although his ideas are good, they usually end in failure and disaster. Encouraged by his late mother, Flint never loses heart. He perseveres through setbacks and finds joy in the world of scientific invention. However, his father can no longer tolerate his endless tinkering and demands that Flint help out in the family store. Meanwhile, to solve the local food shortage problem, Flint secretly conducts research on a super food machine. In his latest attempt, Flint destroys the newly unveiled Sardine Land, but his experiment also yields results. In front of everyone’s eyes, an unbelievable rain of hamburgers falls from the sky! Everything becomes interesting...
