Based on the bestselling books by Diana Gabaldon, this trailer from the upcoming STARZ original series is about a "married combat nurse from 1945 who is mysteriously swept back in time to 1743 and thrown into an unknown world where her life is threatened. Claire is pulled between two vastly different men in two irreconcilable lives." Yeah, totally plausible:

If none of this makes any sense, then you should probably know that it was also written by the same guy behind the crap known as "Battlestar Galactica".
