 Every year, a bunch of grasshoppers come to the anthill and eat what the ants have gathered for them. The "offering", as the ants call the ritual, is a part of their fate. One day in spring, when the offering s preparation has just been finished, Flik, unliked inventor ant, accidentally drops the whole offered seeds into the river. The grasshoppers come and give the ants a second chance to collect food until fall. Flik sets off to find bugs that are willing to fight the grasshoppers (nobody expects him to succeed anyway) and, due to a double misinterpretation, returns with a circus crew, giving everybody new hope. When the misunderstanding finally gets cleared out, there is only little time left for a new plan, which has to work, or else...
