When Emery Whitehill (Aimee Teegarden, FRIDAY NIGHT LIGHTS) was 6 years old, an alien spacecraft crash-landed in her small town and she met Roman (Matt Lanter, 90210), a 6-year old Atrian boy, who sought refuge with her before being taken away by the authorities. Ten years later, the two are reunited as the first group of Atrian teens is about to enroll in high school in a widely scrutinized social experiment to see if humans and Atrians can live in peace.
Both Emery and Roman are surprised at the small-mindedness of their respective communities. Roman's sister, Sophia (Brina Palencia), is excited to make new friends, but their fellow Atrians, Teri (Chelsea Gilligan, "Big Time Rush") and Drake (Greg Finley, THE SECRET LIFE OF THE AMERICAN TEENAGER), openly distrust all humans.
