In a world where everyone believes death has finally been conquered and people can live forever, 120-year-old cop Darius and rebellious, suicidal 24-year-old Christa must investigate the mysterious suicides of seven teenagers. With the promise of eternal life, why would a group of teenagers commit such an act? Was it a cult? A political act? Or perhaps a cry for help from a hopeless lost youth? The two embark on a mysterious, dangerous investigation from which there will be no turning back.
