There is a whole lot going in in the second half of The Last Ship Season 3, as tantalizingly revealed in a new trailer that debuted at San Diego Comic-Con on Thursday.

Across the TNT action-thriller’s next seven episodes, Chandler & Co. will become privy to the Big Bad’s extreeeeemely deadly endgame, launch a hunt for a mole within the White House and do the ol’ Star Trek shimmy-and-shake when the Nathan James takes enemy fire.

On the brighter side, though, the trailer trumpets the return of a familiar face — just in time to ride to the James‘ rescue, perhaps?

Press play above to see what all The Last Ship is ready to deploy starting this Sunday at 9/8c.
