Ensign Boimler welcomes his girlfriend Barb onto the USS Cerritos, much to Ensign Mariner's dismay - while Ensigns Ruthford and Tendi have starship envy when the Cerritos rendezvous with the more-advanced USS Vancouver.
Ensigns Mariner, Boimler, Rutherford and Tendi are the support crew on one of Starfleet's least important ships, the U.S.S. Cerritos, in 2380. They have to keep up with their duties and their social lives, often while the ship is being rocked by a multitude of sci-fi anomalies. The ship's bridge crew includes Captain Carol Freeman, Commander Jack Ransom, Lieutenant Shaxs and Doctor T'Ana.
