In the early 20th century Caine stands up to a man who is terrorizing a town. Also in the town is his wife and their son. Caine only has the drunken deputy and Cheyenne Bodie to help him. One night the man comes into Caine's home and grabs his wife and son and shoots Caine. While Caine is near death, he transports himself to the present and seeks out his grandson--the present day Kwai Chang Caine. When he finds him, he tells him that he has to help his grandmother and father. So Caine goes and along with Bodie and the deputy go to rescue them. (thetvdb.com)
