Pixie and Dixie are enjoying their stay in the cheese factory and the fact that their pal, Jinks, is the guard and is in no hurry to do anything. Unfortunately, Jinks gets fired and is replaced by a new much faster cat named Bullet. The mice quickly learn why the cat is named Bullet because he's almost as fast as one and they are quickly caught and thrown out.
Pixie and Dixie plan to help Jinks get his job back and they try to get back into the cheese factory. They try several ways and each time they are foiled by Bullet. They are caught and thrown out.
Finally, Pixie and Dixie come up with a good plan and paint a rocket to look like a mouse and then they put glue on the rocket. Bullet catches the rocket and can't let go and runs over the boss of the factory who quickly fires him and rehires Jinks. The mice think they have it made again but Jinks catches them and throws them out and tells them that he has to keep his job now.
