What is it about?

This is how Rotten Tomatoes describes this movie:

In this gripping futuristic anime, 10 space cadets have their survival skills put to the ultimate test when their crippled spacecraft is set adrift in the cosmos.

To add a degree of difficulty, one of the cadets just might be an impostor intent on destroying the ship before the wayward space travelers can get home.
