Official Trailer for TIMELESS (On NBC)

ABOUT THE SHOW: "From Eric Kripke ("Revolution," "Supernatural"), Shawn Ryan ("The Shield") and the producers of "The Blacklist" comes this thrilling action-adventure series in which a mysterious criminal steals a secret state-of-the-art time machine, intent on destroying America as we know it by changing the past. Our only hope is an unexpected team: a scientist, a soldier and a history professor, who must use the machine's prototype to travel back in time to critical events. While they must make every effort not to affect the past themselves, they must also stay one step ahead of this dangerous fugitive. But can this handpicked team uncover the mystery behind it all and end his destruction before it's too late?" (www.nbc.com/timeless)

Always down for some "time travel" stories, seen most recently in The CW's "DC's Legends of Tomorrow" and "12 Monkeys". Am intrigued at what the MacGuffin is in this particular instance, and not the obvious time-travel machine itself LOL
