Jacob Steve, an Old Man, died at 116 after living a whole life.

But Jacob always had a dark side, which he always suppressed and hid from others.
However, in the later years of his life, when death was inevitable, he understood there wasn't any point in having wealth, knowledge, or desires if you couldn't have a life to enjoy them.

He became obsessed with fabled immortality and devoted his reaming life to extending his fleeting lifespan, but just like any other failed.

However, he mysteriously got another chance at life and found a way that led to fabled immortality.
But he was also forewarned that the way led to it was filled with blood and darkness!

In the end, Jacob chose it anyway with no way of going back, and it was also the start of his suffering and his icky, brutal journey toward the 'Immortality' he wanted so badly!

On a normal evening, a voice appeared out of no where to give an announcement all over the world, this same evening was also when Dustin was run over by a car while running way from thugs.

As it would turn out, on the D-day, Dustin is one of those that were taken. But, this might turn out to be an opportunity rather than a curse, as some night before this day, something interesting happened.
