Over the course of the first three seasons, The Navy destroyer USS Nathan James has been the central vehicle for the discovery and distribution of the cure to the Red Flu, resulting in near-global recovery. After the chilling events at the end of last season, Tom Chandler (Dane) has given up his heroic titles and responsibilities and sought solace – and anonymity — with his family in a small fishing village in Greece. Meanwhile, Captain Slattery (Baldwin) and the crew of the Nathan James have discovered that the virus has “jumped kingdoms” and now infects the world’s food crops, bringing humanity to the brink of global famine.

The fourth season launches across TNT platforms with a two-episode premiere at 9 PM Sunday, August 20.
