A drama series based on the "Roswell High" novels about three aliens masquerading as human teenagers in Roswell, New Mexico. High-schooler Max Evans miraculously heals his secret love after she is struck down in the local diner by a stray bullet. After saving her life, Max is confronted by the beneficiary of his supernatural powers. He is forced to admit that he and two others in Roswell -- his sister Isabel and his friend Michael -- are the survivors of a 1947 alien-spacecraft crash. They have been living covertly ever since to elude the U.S. government, and Max's love-inspired healing has jeopardized the lives of the extraterrestrial trio. The teens must also band together to outwit local Sheriff Valenti who has long-standing personal reasons for wanting to expose the truth about the 1947 crash.
