He soon learns that nothing will be easy at his new school, especially when he recognizes Emery (Aimee Teagarden). Ten years earlier, Emery discovered a very scared young Roman hiding in her backyard shed and took care of him until authorities found him and violently took him away. But, Roman never forgot the human girl’s kindness.
