From Emmy Award-winning writer-producer Kevin Falls and Emmy Award-winning director-producer Alex Graves, Journeyman is a romantic mystery-drama about Dan Vasser (Kevin McKidd), a San Francisco newspaper reporter and family man who inexplicably begins to travel through time and change people's lives.
Along the way, he also must deal with the difficulties and strife at work and home brought on by his sudden disappearances.
However, his freewheeling travels through the decades reunite him with his long-lost fiancée Livia (Moon Bloodgood) - which complicates his present-day life with wife Katie (Gretchen Egolf) and their son.
Dan's "shifts" through time occur seemingly at random. The only indication he has to an oncoming jump is a feeling in his head which varies from right before he jumps to several seconds of warning.
Dan appears to have no control over the shifts. The first jump is typically several decades into the past; through a series of jumps, he jumps nearer to the present, usually years at a time.
The jumps manifest themselves with a small blue flash and a ripple as Dan appears to vanish from the present, and appear instantly in the past. He is missing from the present for a period of time unrelated to the period he spends in the past.
Dan does not arrive in the same location he departed, but instead arrives near the person who he is supposed to help. His jumps are typically restricted to the area he leaves from, usually keeping him in the San Francisco area.
Dan is also trying to figure out the mechanics of his travels. He has questioned a physicist who seems to have known his father in the past, and has discussed the possibility of tachyon particles being able to cause time jumps.
It is now clear that the scientist is aware of Dan's travels, as well as those of others like him. It has also been discovered that those born around the time of a rare passing comet have this ability.
Dan's journeys appear to each have an innate purpose, which is not always apparent to him, but involves positively changing the destiny of a certain person. Likewise, fate seems to conspire against him if he tries to alter other events beyond his current charge.
Alterations Dan makes to the timeline affect the present and the memories of everyone in it. His own memories, however, are unaltered, and he recalls events as they originally occurred before his interference.
Dan is not alone in his tendency to time-travel. His ex-fiancée Livia, thought to have been killed in a plane crash, actually traveled back to her "home time", 1948, from where she jumps forward in time.
Dan meets Livia on his jumps into the past, as she jumps into her future to offer her experience and assistance with Dan's missions.
