“The Last Ship” has some of the highest stakes in television history: Should the heroes of the upcoming TNT drama fail in their mission, the entire world dies. There’s a little bit of pressure.

Fortunately, both the show and its characters are up to the challenge, as seen in an extended promo video for the summer series.

Executive produced by Michael Bay and starring Eric Dane (“Grey’s Anatomy”), Rhona Mitra (“Strike Back”) and Adam Baldwin (“Firefly,” “Chuck”), “The Last Ship” is the story of the U.S.S. Nathan James, a Navy destroyer that avoids catastrophe when an unknown virus attacks and kills much of the world’s population.

It’s more than just a virus free haven on the ship too: The scientist (Mitra) most likely to develop a vaccine is on board. And everyone still standing wants the cure she might create.

“The Last Ship” premieres Sunday, June 22 at 9 p.m. ET/PT on TNT.
