Logan goes back in time to 1888 in London to keep the faux Jack the Ripper from changing the future. He discovers that the faux Ripper's plan is not to repeat the original path, but to continue killing women, thus drastically changing the future. Logan manages to send a message to the future by using a drawing of the faux Ripper that the possible next victim drew to send a finger print and a tiny message from himself, the words ""Logan's Graphics"", that not only let those waiting in the future for him know that he was OK, but who the faux Ripper was. The show ends with a showdown in Big Ben where Logan defeats the faux Ripper and returns to the future. The past remains relatively the same and the danger is, for now, at least, safe.

Logan goes to Hollywood, California in 1956 to stop Ian Pascoe (a.k.a. Jack the Ripper) from murdering actress Rita Lake, who will be the mother of the 44th President of the United States. Logan protects Rita from Ian's plot to kill her thus saving history once again. Logan's co-worker Claire Hemmings went back as well after they spotted more danger and also assisted in saving history from being altered.

Logan goes to 1928 after Ian Pascoe abducts Hemmings to ensure he'll get his time-jumping watch back. Logan follows as he encounters danger since Pascoe has been in 1928 before and is a friend of Al Capone and Eliot Ness. While Hemmings and Logan are in 1928, the people in 2007 discover that Pascoe has made himself a part of several periods of time. They also figure out Pascoe's hint while he was in custody: A delivered note that Pascoe says in giberish and could have ""Been written by a 13 year old"", which is what Pascoe was in 2007. Finding the 13 year old Pascoe could save the future and history. Logan recues Hemmings, but Pascoe gets away with his watch.
