This one is a long one, but the movie ties in with all previous 3. The story takes place 4 years after beating the corrupted of the Insane Asylum.
Aaron is secluded, tired, peaceful, and not really a people person anymore. He starts receiving pictures of Gordon (character in the original flatline). Pictures of Gordon before the events that took place in the original flatline. Soon into that story, he starts receiving random phone calls from someone saying he/she is Jake.
This story was a bit more challenging. Not only did I just make up a usual story, but I tied in events that were from the previously three, kind of like one big set up.
Besides Flatline 2, this is definitely my favorite of the series. I hope you enjoy, and I am putting the finishing touches to it.
