From ABC -

At all corners of the Earth humans awaken to the sight of spaceships hovering over every major world city. As ominous as this sounds, we have to admit, it sure beats coffee as the go-to morning pick-me-up.

Jokes aside, the ships’ occupants, known only as “The Visitors,” spread their message quickly and clearly: They have come in peace, bearing gifts of medical miracles and technological breakthroughs far beyond earthlings’ wildest imaginations.

Many of the world’s citizens have been enamored by the aliens and their generous offers, believing every word The Visitors utter. But while on assignment, Homeland Security agent Erica Evans discovers their intentions are anything but altruistic: The Visitors’ claims of peace, generosity and doing no harm are… (pregnant pause)… LIES! They choose to attack by means of guile instead of warfare, infiltrating our governments and businesses in an attempt to subjugate and dominate mankind. Yet even with that knowledge, how can Erica convince others of the truth when The Visitors wield two subtle but formidable weapons from their vast arsenal?

First, with amazing gifts and persistent claims of harmony that The Visitors have demonstrated, many would laugh in Erica’s face or worse. Second, The Visitors have the world’s youth on their side, recruiting many—including Erica’s son Tyler— as 'Peace Ambassadors’. But in actuality these captivated youngsters are actually serving The Visitors as unsuspecting spies. With little options on preventing this invasion, Erica becomes part of a growing resistance of people who have seen through The Visitor’s lies like her. But will she be able to help thwart this invasion as well as keep her son safe?

The world is shaken up by a mysterious group of ships hovering over their cities.
