Midshipmouse First Class Chester and his band of rodents are tail-pumped to graduate from the Naval Mouse Academy and commission as officers in the Fleet of the Corps. It is simply a matter of finishing strong in their final year of training, staying on top of the game, and achieving their goals at service and ship selection. Piece of cheese.

But when the academic year begins, troubles crop up like mouse traps, and their leadership skills are put to the test. Chester's attempts to help a plebe overcome failing grades and a youngster avoid expulsion are interrupted when a dangerous predator takes up residence on the Yard and the situation becomes dire. Who knew the call to serve would arise so soon?

Unaware of the midshipmouse training program, human midshipmen in the rooms below balance rigorous responsibilities with duties while giving one last push to rid their quarters...of mice.

Then the unthinkable happens and an unforeseen obstacle threatens Chester's own dreams for the future.

Though the needs of the Navy come first, both brigades of mice and mids keep fingers and claws-crossed that three years of hard work will pay-off at service selection.

Who gets their first choice and who does not? Who earns their dream to weigh anchor on the salty sea and who will dive to the depths? Who will pursue their wings of gold and whose fur is shaved bald between the ears?

Time and tide will tell.
