Jack the Ripper – the first serial killer. Hundreds of years later, “Ripperologists” study his crimes to determine his true identity.

The Near Future. One detective team has the means, motive, and opportunity to solve the case once and for all – they plan to travel in time, catch The Ripper in the act, discover his identity and bring the guilty man to face modern justice.

Whitechapel, London, 1888. A forensic psychiatrist and homicide detective duo arrive in the past to investigate the Ripper’s crimes before they happen. They draw closer to one another and consummate their feelings for each other.

The time comes for the first murder, and the victim remains alive and well. So does the second. But then a day arrives when terror has already struck, those women have been dead for weeks, and the body of a third Ripper victim has been found.

As fear grips London, only the time travelers know the dark secret. Just as they’ve found their own love, they wonder – did opening a window in time bring Jack with them?

Nothing is as it seems when the future impacts the past…It’s a race against time to end the Ripper’s perfect crime spree. Will they be able to stop the serial killer watching them before he returns to their own time and vanishes anonymously – again?
