In the not so distant future, Lily lives with her family in an old house in the city. One day, in the Solikamsk chemical laboratory, an unfortunate explosion causes a toxic cloud of colossal dimensions that expands, covering meadows, mountains, rivers and cities. Inadvertently, its toxic effects generate a cellular alteration in the smallest bugs, whereby they mutate to a surprising size. One of them stands as a leader in the rebellion against the mistreatment they have suffered from humans for centuries. As mutants try to raid Lily’s house, she and her grandfather come up with a crazy idea to save their family. There are runs, power struggles, chases and punches. And, above all, a lot of insects.
