In Part 1, it's the year 2020, and two senior citizens, Jim Chase, a retired community college philosophy professor, and Blake Huntley, a guitar teacher, are on a zoom call and reminiscing about a day in 1969 when they took some LSD together. Shortly after the two young men went their separate ways while peaking on a suburban street, Blake was arrested for disorderly conduct. Jim and Blake met up again at the end of the following day, after Blake was released on his own recognizance, by which time they had each lived through what seemed like several lifetimes. As the two old friends share recollections of what happened from their respective points of view, the trip comes alive again in all its heights and depths, and we are reminded of what made that period of history special.In Part 2, it's the year 2034. Ms. Doris Dawes, a representative of Floral Acres Memorial Park, is speaking to an audience of reporters. A mysterious box had been found in the grave of the late James Chase. It contains a notebook with handwritten entries dated from May 29 through December 8 of the year 2056. Both the box and the notebook exhibit unusual and as yet unexplained physical properties. The bulk of Part 2 consists of a transcript of the writings in the notebook which has been published on X by Javier Martinez, an investigative reporter who had been present at the press conference. The writings consist largely of philosophical and religious speculations about the afterlife and other possible worlds. Experts have deemed them to be of little value, but Mr. Martinez is not so sure. What he is most interested in, however, is whether there ever really was a magic box and notebook. Was it all just an elaborate prank made to look like a message from beyond the grave, set up by the late James Chase and some accomplices, including a certain Blake Huntley?
