Looks like the crew of Navy destroyer U.S.S. Nathan James won’t get even a bit of good news in season 2 of TNT’s “The Last Ship.” An ominous new trailer teases that “a new enemy will surface” when crew members finally make it to the U.S. and try to find their families.

The new season makes landfall with a two-hour premiere at 8 p.m. June 21, right smack in the middle of TNT’s packed summer lineup.

When “The Last Ship,” based on William Brinkley’s novel, premiered last summer, it’s global pandemic story thrilled millions of viewers who made it the No. 1 new show on basic cable in a couple of demos, according to TNT. Last season, Captain Tom Chandler (Eric Dane) and his crew were tasked with helping Dr. Rachel Scott (Rhona Mitra) find a deadly virus that sparked a global plague that has wiped out 80 percent of the world’s population, then create a cure and get it to the U.S. They faced down many hellish roadblocks along the way.

In the new season, our heroes are back in the U.S., but it’s not a celebratory homecoming at all. “The Chosen” are seeing to that. (Just check out the trailer above.)

It will be another busy summer for TNT, which has 10 original series—three new ones—premiering over the three-month season. “Proof,” “Public Morals” and “Cold Justice: Sex Crimes” joins the roster this summer that also includes the fifth and final season of the hit alien-invasion drama “Falling Skies,” which begins June 28.

TNT’s summer begins June 8 with the season 4 premiere of “Major Crimes” starring Mary McDonnell, and the second season of “Murder in the First.” Taye Diggs and Kathleen Robertson return to “Murder in the First,” which will again focus on a single murder investigation for the season.

On June 16, “Rizzoli & Isles” returns for its sixth season followed by “Proof,” in which a surgeon (Jennifer Beals) explores the perplexing question of whether death truly is the end, or if there’s something else beyond. Matthew Modine, David Sutcliffe and Joe Morton also star.

TNT’s real-life crime series “Cold Justice” gets a spinoff, “Cold Justice: Sex Crimes.” Both shows debut July 31. “Cold Justice: Sex Crimes” sees former Texas prosecutors Casey Garrett and Alicia O’Neill help small-town police close cold sex-crimes cases.

Another newcomer, “Public Morals,” premieres Aug. 25. Written and directed by Edward Burns, “Public Morals” takes viewers to the seedy streets of 1960s New York. Michael Rapaport and Elizabeth Masucci also star.

TNT has canceled its former summer dramas “Dallas,” “Franklin & Bash” and “Perception.”

May 6 Update: TNT has moved the Season 2 premiere of “Legends,” starring Sean Bean, to the fall. “Public Morals” moved to Aug. 25. This story has been updated.
