Falling Skies season 5, which will also be its last, will premiere on 28 June at 10pm on TNT.
The final season will feature one final battle between humanity and alien race Esphenis, which will determine the fate of the earth.
"There is one more fight, and nothing will be as it was," says Tom Mason in the Falling Skies season 5 trailer.
His voiceover plays throughout the entire trailer: "A man walks through his life. He stumbles and he falls. At times, he thinks he cannot get up, but he does, over and over until one day, when the man cannot hold up the sky falling all around him anymore, and he reaches his journey's end. But there is one last fight, and nothing will be as it was."
In the season 4 finale, the 2nd Mass did destroy the Espheni's power core, but Tom is seemingly lost in space in an Espheni ship and is now caught in some kind of waking dream. His last words in the finale were: "You're beautiful."
According to reports, season 5 will give viewers the answers they have been waiting for questions such as, why the Earth was invaded by the Espheni.
Drew Roy, who plays Hal Mason explained the presence of aliens and said that the reason they came to Earth in the first place, will be tied up with the new creature that intercepted Tom Mason's ship in the season 4 finale.
"It does come to an end; we explain why they're (the aliens) here (and what) their motives (are)," Roy said at WonderCon, according to TV Equals. "[The] figure seen at the end (of "Shot the Moon") is the catalyst (who is) tied (to their) interactions."
A press release for the final season indicates that he won't be the only human ready to see the backs of their fishhead overlords.
"As season five opens, all breed of beast and mutant are running rampant on earth," TNT teased. "The Espheni's power core has been destroyed, and humans are now ready to fight on their terms, even if it means resorting to hand-to-hand combat against the enemy. After four years of being tortured, imprisoned and mutated and having their loved ones stolen from them, Tom and the 2nd Mass are filled with rage, ready to destroy the enemy in an all-out battle to determine the fate of Earth."
Will "The Final Battle" mentioned in this promo leave the natives of Earth victorious? We will have to wait till June for the answer.
Showrunner David Eick told Flickering Myth that season 5 is already being filmed.
"We just finished breaking episode 5 today, and we don't start shooting for another month or so, so we're in really good shape ... much better shape than frankly I've been on other sci-fi visual effects shows where you're chasing your tail by episode three. It's nice to plan ahead, it's nice to be able to perfect it," he said.
"At the same time, it's nice to be able to make course corrections, and give yourself the flexibility to change things on the fly."
"We're still here, and we'll be back for a fifth and final season. So rarely in television do you get to choose your own ending," added Noah Wyle.
"You get to give the fans a sense of completion to the narrative that you've played out. Getting to wrap up these storylines and have these characters reach their natural conclusions... I think it'll be satisfying for everybody."
The show follows the life of Tom Mason, a college professor who becomes an unlikely resistance leader following a massive invasion by an alien race known as the Espheni.
