Journeyman is a romantic mystery-drama about Dan Vasser, a San Francisco newspaper reporter and family man who inexplicably begins to travel through time and change the course of people's lives. Along the way, he must also deal with the difficulties and strife at work and home brought on by his sudden disappearances. His freewheeling travels through the decades reunite him with his long-lost fiance Livia--which complicates his blissful, present-day life with his vivacious wife Katie and son.
