The programme promised heightened sensory and intellectual abilities, it was a race against time to vindicate mankind. Pain, an orphaned baby on the brink of death, obtained salvation in the PNE programme. However, before the programme was shut down, the lead researcher, Dr. Dante Bell mysteriously disappeared along with Pain.  17 years later, Pain and Dr. Bell make their majestic appearance, albeit under new identities, leading to a chain of events that will forever change the course of mankind's destiny!
