On the day a boy is supposed to become a man, his entire world is turned upside down as everyone he knows is transformed into insatiable flesh-eating monsters. In an attempt to save his mother and sister's life, he flees their home to lead the cadaverous creatures away. The boy's act of gallantry won't be his last as he embarks on a journey fraught with danger, death and sacrifice. To become a man, the boy will have to face these challenges while protecting and leading a group of child-survivors through the nightmare that has become their reality.
