Star Trek: Lower Decks is the second animated series in the franchise and its first-ever comedy. It charts the intergalactic adventures of bottom-rung staff and their beleaguered superiors aboard the USS Cerritos, one of Starfleet’s least consequential vessels.

In season 3, Beckett Mariner’s disobedient antics saw her exiled to Starbase 80 before saving her friends from rogue AI-powered ships. The usually timid Brad adopted a bold new approach to career advancement — including agreeing to be hunted by an alien warrior called K’ranch — and Rutherford regained his memory to uncover the truth behind his Vulcan cybernetic implant and a treacherous scheme by Admiral Buenamigo.

Expect season 4 to continue to follow our beloved “lower deckers” as they take on new roles and face intergalactic foes old and new. An unknown enemy has begun targeting United Federation starships. Brad, Beckett and friends are looking to prove themselves capable, joined by provisional ensign T’Lyn, a fan-favorite character who'll become a regular member of the team. Meanwhile, corrupted AI hologram Badgey is set to return, ready to torment his creator Sam Rutherford further.

Star Trek: Lower Decks season 4 trailer

As the trailer opens, an unknown force is indiscriminately destroying starships. As it turns its guns on Starfleet, the USS Cerritos is called in to help. “I guess we’re finally getting some respect”, Beckett Mariner muses, as Brad begins Holodeck waste disposal. 

But with the promise of promotion in the air, they’re determined to prove they can be more than just “Lower Deckers” — battling returning AI villain Badgey, handling fraught encounters on a visit to Orion, and promising that whatever happens, “we’ll be friends forever no matter what our ranks are!”
