Efter den episk spændende afslutning på anden sæson, skifter Nathan James’ besætning deres fokus til Asien. Præsident Michener har nemlig hørt rygter om at den kinesiske leder, præsident Peng, har hamstret store mængder af ‘Scott Kuren’, i stedet for at fordele den til folket i regionen.

Michener sender Chandler til et globalt topmøde, for at efterforske dette, samt for at undersøge rygterne om en mulig mutation af den originale virus, der har forårsaget et nyt udbrud i Japan. Hvis mutationen har fundet sted, og Asien ikke er blevet beskyttet, er konsekvenserne for verden dystre.

Meanwhile, Captain Slattery and the crew of 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. As the ship traverses the Mediterranean in search of a solution that can save the world's food supply, Chandler encounters his own enemies in Greece. His “hero’s journey” becomes a modern day retelling of Homer’s Odyssey.
