Some vacationers are enjoying a relaxing day at the park when they are interrupted by Professor Von Gimmick and his giant four legged robot he calls the Big Gimmick. He plans to use this machine to take over the world and he is going to start by crunching some buildings in the big city.
Atom Ant has just finished excercising when he receives the distress signal and flies to the city to find out what's going on. He finds the professor pushing over a building with his machine and Atom Ant stops the building from falling. The professor tries several things to get rid of Atom Ant and they all fail. He gets the idea to set up a picnic to lure Atom Ant away. It almost works, but Atom Ant overcomes the temptation and takes the machine and flies it up into the air and drops it. Now the professor is in the scrap iron business since that's all that's left of his machine and Atom Ant goes to the picnic to enjoy himself after a hard day's work.
