In this compelling series about the world's first encounter with an alien race, appearances can be deceiving. Simultaneously emerging and hovering over every major city in the world, the Visitors (or V's) promoted a message of peace, urging mankind to unite and claiming that Earth could learn much from the wonders of the V's technology. While the world quickly embraced the V's as saviors, FBI Counter Terrorist Agent Erica Evans (series star Elizabeth Mitchell)--at the time, investigating a terrorist cell--discovered that the Visitors were not who they said they were, and that they and their leader, Anna (series star Morena Baccarin), were after something far more devious and diabolical than anyone could imagine: the destruction of humanity.
