Let me preface this review by saying“I liked this movie!” It has plot holes big enough to drive a truck through, but it also has all of the Alien franchise classics
Jake and Bill go to Dallas. They find out they're not the only ones looking into Oswald. Jake also tries to blend in and is hired as an English teacher at a local school, where he re-meets Sadie, who's the librarian of the school.
Jake stays around Harry's hometown to prevent Harry's father from murdering his family. Things go south fast as he gets too close to the family and ends up messing the time line.
Jake's life takes a new turn when his friend shows him a time portal to 1963. He then goes back to try and stop the assassination of JFK. Meanwhile, he makes a life of his own in the '60s and nearly gets arrested.
