After being told he shouldn't play under the hood of the car, Mus doesn't listen to his Mommy. When the car starts up, it's too late for him to get down and he finds himself going on a journey. Alone and afraid, the little mouse doesn't know where he is when the car finally stops. He breaks another one of his Mommy's rules when he talks to some strangers, asking them for help to get home. Will these strangers lend a hand to get Mus back to where he belongs, or will he need to figure out how to find his Mommy on his own?
