Dozens of UFOs suddenly appear on Earth, hovering over major cities around the world and claim that their objective is to help the Human race, providing vastly superior intelligence and technology in exchange for water and minerals only found on Earth. The leader of the Vs, Anna, uses popular TV anchor Chad Decker to deliver her messages to the Humans, but suspicion arises from FBI investigator Erica who believes that the Vs have different intentions to what they claim.

Chad reports from the Peace Ambassador Center as 100 diplomatic visas are being issued to the first wave of American Visitors, with Anna getting the first, but not everyone agrees with the decision. Erica has been tasked to protect the Vs and is tracking a death threat while paired with a V officer. Meanwhile, Ryan starts reaching out to his old friends to build up opposition forces and help fight the Vs.

Erica works with new allies to uncover a biological threat they suspect the Visitors have been plotting. Aboard the mothership, Anna meets with a special guest, while managing the investigation into the murder of a V. Chad does a segment on the V Healing Centers demonstrating their amazing medical abilities, but finds himself conflicted by some of his findings.

Erica finds her life in danger when she's attacked at home. A dangerous new member is recruited for the Resistance as the Visitors shore up their defenses. Anna wonders why Chad hasn't followed up on his diagnosed aneurysm and Ryan's concern grows over Val's "abnormal" pregnancy.

Anna introduces her pilot program to invite select groups of humans to stay on each of the 29 space ships. Ryan must deal with the fact that Valerie's pregnancy is wildly accelerated. Tyler learns a secret about his mom and one of the team makes a sacrifice to save Ryan.

Erica, Ryan and Jack go on a harrowing mission to find the legendary John May in order to rescue Georgie. Anna brings Chad aboard the Mothership for a story on her Live Aboard Program and Tyler confronts his mom about his mysterious past.
