The former crew of the U.S.S. Protostar and now warrant Starfleet officers in training - Dal, Rok-Tak, Zero, Jankom Pog, and Murf - are reunited for an internship under the command of Admiral Janeway.

Thanks to Wesley Crusher's timely intervention, the cadets find the Protostar - but the ship's marooned guardian isn't eager for their assistance.

Chakotay and the cadets devise a bold but perilous plan to relaunch the Protostar. Before the ship can fly, however, it will first have to sail.

While harvesting bosonite on a barren world, the crew encounters aggressive, genetically-modified tribbles - and the Klingon scientist who created them.
