Man in modern day is struck by lightning and transported 1000 years back in time to same spot. Survives animal attack but barely. Nursed and mentored by old ancient native american. Man communicates with present day wife through cave writing which is found by archaeologists in present. Archaeologists date writing and find it is authentic but still skeptical as writing is modern English. Man never gets home to present day. Starts new life in past with native american woman. Thank you!
