It's been four seasons since Ant Island was set free from Hopper's tyrannical reign.
Atta and Flik are happily married. Their small wedding ceremony was attended only by the Queen, Princess Dot, the Royal Council, and the circus bugs. It was an evening filled with music, dancing, and — for the first time any of the participants could remember — an abundance of food.
Tragically, a few weeks after this joyous occasion, the Queen fell ill and passed away. The throne was left to her eldest daughter, who inherited the role with grace and dignity amidst her deep sorrow. Although the royal family continues to grieve the death of their matriarch, the colony as a whole is enjoying a time of peace and prosperity.
Flik's technological advancements have gained widespread fame, catching the attention of nearby colonies as well as other insect communities. Under the supervision of Queen Atta and the Council, the new prince consort partnered with the island's Head of Engineering, Thorny, to build a larger workshop, hire over fifty employees, and set up a trade system with neighboring kingdoms. Flik also recruited Dot as his honorary lab assistant — a decision made partly because he saw the antling's budding brilliance, and partly because he knew she needed a healthy distraction from the sudden loss of her mother.
After spending some time as traveling performers, the circus troupe made the decision to set up a permanent attraction on Ant Island. Their circus has drawn visitors from all over the Insect Realm, which has only served to increase the island's growing wealth and prominence. After years of enslavement and oppression at the hands of bigger bugs, the residents of Ant Island can finally draw a breath and relish in the fruits of their labor.
What the colony doesn't know, however, is that elsewhere — in an anthill not unlike their own — trouble is brewing.
Flik has a rival, an ant who is like him in every way…except for one very important difference.
His heart.
