Charlie(the rat) was in his dreams when he was seized to be spoonful succulent appetite of two other cats "Ronny" & "Booggie". Ronny is the one who calls th shots and Booggie is lean, quick and always ready for rats. Charlie being trapped between the worthless cats stay dauntless and comes up with a plan. He acts as a heart patient and falls down just to make cats meal of unpleasant dead rat and to be thrown away. Cats are astonished looking at the rat then its time for the cats to run for their life when Bigbull (the dog) joins their company. Bigbull is contemptuous well build cat hunter and every heroic entry makes him more high headed and pompous. The ground breaking dog and cat chase is  interrupted by Charlie with positive demeanour who teaches them a good lesson and get triumph over the situation . Its perfect example of setting an aim and achieving it with a possitive attitude.
