A still from Childhood's EndSyfy

The three-night miniseries Childhood's End will air its final chapter titled The Children this Wednesday, 16 December. Fans and viewers will finally get to know what lies in store for mankind as the epic alien invasion event comes to a conclusion.

The synopsis for The Children teases: "A new age dawns as children begin to exhibit advanced abilities, but it's unclear what this means for the future of humanity." Check out the upcoming episode's promo here.

So what can fans expect from the series finale? Without giving away any spoilers, Syfy president Dave Howe told IBTimes UK: "This isn't just about an alien invasion; this is about the next chapter in humanity's evolution. It really does take you all the way through to not just the end of the world but the beginning of a new existence for humanity."

The first two episodes of Childhood's End — The Overlords and The Deceivers — have been well received by audience and critics alike and it will be interesting to see what sort of response the finale generates.

Childhood's End Night 3 (episode 3) The Children airs on 16 December on Syfy at 8.00pm ET. Click here to watch the finale live stream online.

Childhood's End follows the peaceful invasion of Earth by the alien Overlords, who promise to eliminate poverty, war and sickness – ushering in a golden age of peace, health and security for all of humankind.

But why do the Overlords insist on hiding their appearance – and what do they ultimately want from Earth? While much of the world enjoys its newfound utopia, some suspect there's a price to pay.

As the truth about the Overlords' intentions are revealed, humanity will discover its actual destiny may actually be a nightmare, instead of a dream.
