Sylvester Cat must catch mice or lose his happy home. When he can't find a mouse inside, he searches out of doors and comes upon one meek, little mouse who agrees under duress to be Sylvester's one rodent to catch and rough up again and again in front of his masters. But it isn't long before the mouse realizes Sylvester needs him alive and decides to stop being Sylvester's stooge.
