The Season Two opener, "Red Rain," continues the action from last season's finale when Anna unleashed Red Sky on the planet. With the world on the brink of war and chaos all around, is there anyone who can stand up to Anna? Meanwhile, Ryan has been kept in isolation on the mothership, away from his hybrid baby so that Anna can experiment on her. Chad, seeking redemption for being used by Anna, now wants to fight with the Fifth Column, and Erica goes on a journey to find a scientist who can give her the answers to what Red Sky is, and where she learns the horrifying secret of what the Vs are doing on our planet.
