Season 1

A young H.G. Wells travels in the time machine he created to modern day New York City in the pursuit of the charismatic (yet secretly psychopathic) Dr. John Stevenson, better known as "Jack the Ripper."

Presented with the real possibility that Vanessa Anders is in fact Wells' great granddaughter, H.G. and Jane continue to search for Dr. John Stevenson, but when their final face-to-face meeting goes anything but planned, the doctor is back

H.G. and Jane rush to repair the damaged time machine before Dr. John Stevenson - now better known as "The Key Killer" - strikes again. Meanwhile, Vanessa must decide whether or not to confide in Griffin.

Dr. John Stevenson has met his match in a stunning - and equally cunning - doctor named Brooke, while H.G. and Jane travel back to the 1980's where they make a shocking discovery that could change Vanessa's life.

After learning John has taken the time machine to 1918 in Paris, H.G. is determined to stop him before he can alter the fabric of time.
