Journeyman is a new show on NBC, Mondays 10pm.
From the site:
From Emmy Award-winning writer-producer Kevin Falls ("The West Wing") and Emmy Award-winning director-producer Alex Graves ("The West Wing"), "Journeyman" is a romantic mystery-drama about Dan Vasser (Kevin McKidd, "Rome"), 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, "Day Break") -- which complicates his present-day life with wife Katie (Gretchen Egolf, "Martial Law") and their son. Reed Diamond ("Homicide: Life on the Street") and Charles Henry Wyson ("The Curious Case of Benjamin Button") also star.
I haven't seen it yet, but I'll probably catch it online this weekend.
