After a high profile mission goes awry, Boimler is further plagued with self-doubt when Mariner proves herself to be a more naturally talented sci-fi badass than he. Rutherford quits his job in engineering and explores other departments on the U.S.S. Cerritos.
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.
