WonderCon has this description for the Last Ship panel:
The Last Ship returns to WonderCon for a first look at the upcoming season and a panel with producers and cast including Adam Baldwin, Bridget Regan, Travis Van Winkle, Marissa Neitling and Jocko Sims. Following the epic season two cliffhanger, the highly anticipated third season finds the crew of the Nathan James shifting their attention to Asia after President Michener hears rumblings that the Chinese leader, President Peng, has been hoarding the “Scott cure” instead of distributing it to the people in the region. Michener sends Chandler to a global summit to investigate this allegation, as well as rumors of a possible mutation of the original virus that has caused a fresh outbreak in Japan. If the mutation has occurred, and Asia has not been protected, the consequences for the world are dire. And with Rachel Scott shot in the season 2 finale and her fate as yet unknown, hope is in low supply. Panel attendees will be treated to never-before-seen footage and a revealing discussion led by TV Guide’s Rob Moynihan. All new episodes of The Last Ship air on TNT this summer.
The panel is Saturday March 26, 2016 11:00am – 12:00pm in Room 408AB so be sure to head there early as the room will fill up quick. No word yet on whether TNT will also do a signing for The Last Ship, so pay attention to TNT on Twitter for the WonderCon updates on that.
