1888, Whitechapel. A woman wakes in a dark alley where a murder has just taken place. She can't remember her name or how she got there. Only later does she learn the man in the alley with her was Jack the Ripper. Soon she realizes she has been thrust more than a century into the past. And what of the fate of her daughter who was with her when this catastrophic timeslip occurred? She can only hope she too was not transported to the past. Striving to keep the secret that she is from another time, she tries to adapt to a world that is foreign to her while desperately trying to figure out how to return to her own time. As the grisly murders pile up, Inspector Abberline of Scotland Yard wants to know who she is and how she is connected to the Ripper. To her surprise, she finds herself falling in love with the shrewd detective, but if she stays in his time, she may be the Ripper's next victim.
