On the spaceship Umiak, an elite troupe of cadets is forced into servitude by an unscrupulous captain taking the ship to a smuggler's rendezvous. During the transaction aboard the eerily silent Virginia, the cadets unwittingly transport an unexpected cargo: a hive of hibernating aliens. As the aliens begin to awake, a terrifying battle erupts between the cadets, the smugglers, the captain, and the emergent monsters. The cadets soon realize that in space, no one can hear them scream.
