Oggy is sleeping on the couch, While Jack is playing with Toy soldiers, making noise and disturbing Oggy. Oggy sents Jack to play outside. Jack gets to the basement and takes his helmet and Toy rifle, as the cockroaches began to make a fake war. Cockroaches use smoke, sound effects, and even make a scenery around to depict an ongoing war. Jack, thinking it's a real war, begins to cry. Then Jack wears a mask to prevent from position ( which is actually fake smoke.) He uses military tactics to reach the Oggy, who is at the time exiting the house to dry laundered clothes, knocks him in back in the house. Jack tells Oggy that there is an ongoing war, but Oggy doesn't believe him, thinking he's got crazy. Jack cries when nobody believes him and jumps behind a hedge to avoid fake gunfire, causing him to fall in Bob's pool breaking the bob's statue, prompting bob to beat him. upon seeing fake troops marching, he throws a grenade at them, well.... mostly he threw the pin. He warned Oggy. Jack, upon realizing he must warn Oggy, he rolls back in the house through the chimney and warns Oggy, to which Oggy knocks him out of the house. Jack, realizing he lost his gas mask, attempts to enter the basement but the doors turn out to be locked, causing Jack to cry again. Jack notices the cockroaches with the key, but Dee Dee ate it away. Giving the cockroaches a long chase, exhausted, he rests against the background, causing it to knock down, making Jack realize it was all a fake prop. After a while, Jack is painting war-themed paintings in the lawn, Oggy sees it inside his house in the window, and Jack waves the hand like is saying "hi" to Oggy, and Oggy also waves the hand to him, and leaves. Once he's done he reveals the cockroaches (tied up with dynamites), and sends them through the paintings, after a while the dynamite explodes and Jack laughs as the episode ends.
