I think it was made in the 80's but not sure. It starts with these time traveling people and one of them decides to try and kill the others by going after ancestors in the past. There is a father and daughter, a man and a women, and they follow after the guy is is trying to kill them and change the future. They all wind up in the renaissance age.Where the one guy is trying to wipe out the father and daughter by killing someone called (i think the red knight). Anyway the daughter winds up falling in love with her own ancestor. They catch the bad guy and go back to there present. The daughter winds up going back to the past to be with her knight and becomes her father's ancestor. If anyone can help that would be great.
