While out riding his motorcycle Stephen Paterson witnesses a fatal motoring accident in which the motorist is killed and a motorcyclist is seriously injured. This incident sets in motion a series of developments which completely change the lives not only of Stephen himself but also of the injured motorcyclist and all his friends. Because of a heavy blizzard he offers four of the friends overnight accommodation in his home. During that night he learns of the tragedy in the early life of the injured motorcycle, of two tragedies in the developing years of another of the friends. He also learns how that friend became the life partner of the injured motorcyclist. During the overnight stay Stephen learns they are all gay, part of a group of gay motorcyclists. To Lay a Ghost - Trigger is a romance, an old-fashioned concept but set in modern times at the turn of the 20th century.
