Using the 1979 novel and movie as a starting point, Time After Time will chronicle the epic adventures of young H.G. Wells and his Time Machine. In the book and and in the feature starring Malcolm McDowell, David Warner and Mary Steenburgen, H. G. Wells - the bestselling author of The Time Machine and War Of The Worlds - has invented a time machine. He shows the contraption to his friends, oblivious to the fact that one of them, surgeon Leslie John Stephenson, is in fact the infamous Jack the Ripper. When Scotland Yard detectives get on Stevenson's trail, the murderer uses the time machine to flee to the future, getting transported to 1979 San Francisco. He is quickly followed by Wells who is trying to bring him to justice.
The show follows the character of Emily Thorne who returns to the Hamptons with one firm goal to get revenge on those responsible of destroying her family.
