ENTERTAINMENT WEEKLY:Every season brings about new challenges for the crew.
Its a mutation ofthe Red Fluthat affects crops.
Thats the engine that drives the mission.

Who specifically will they be combatting to stop the Red Rust?
So thats one gang.
Theres also a Greek mafia gang that are in cahoots possibly with the Greek city-state in this post-apocalyptic world.
Well see that a lot of the former countries of that region are no longer countries.
Its back to the ancient Greek times where you had city-states rising.
Its a multinational operation that takes them on a journey all along the Mediterranean.
Sounds like quite an exotic journey for the ship.It really is.
We kind of mirror a lot of that storytelling hopefully subtly, but sometimes overtly.
And where is the ships Odysseus in all this?
Wondering if he everwantsto go back.
And so the question is can he really fight his destiny?
Can he refuse the call to action once again when the world needs a hero?
But since then, hes become an icon.
Production on the show was shut down for a while to let Eric Dane cope with depression.
Did having that time off for the show change it in any way?
Every episode we make is like a brand new feature film really.
If you dont have time, you have to have money.
You have to have one or the other.
We definitely used the time.
The Last Shipseason 4 kicks off Sunday, Aug. 20, at 9 p.m.
