Ingesting cannabis in the form of a cake has a remarkable effect on the brain, it slows down perception and effectively the time continuum. Professor Connors discovers this on a trip to Amsterdam. As a neural biologist he is intrigued with the effect and after dedicated research is able to identify the area of the brain that interprets and coordinates time.
He isolates the active ingredient in cannabis, refining it to a highly concentrated pill that he calls a 'lucid'. The effect is to slow down time so much that it opens up the time continuum and he is able to enter a parallel universe or reality. He designs the 'lucid' so that one second of normal time relates to 2 weeks in another time dimension. This is very exciting until somebody in the trial, whilst in the other dimension, is killed. Professor Connors is on trial for murder and has an impossible case to defend until somebody on the jury takes a 'lucid'.
