Eventually, Jakob arrives in London's East End, trying to blend in and, hopefully, disappear in the notorious streets. The year is 1888, and Jakob meets Jack. Together, they form a macabre pact where Jack will happily kill for Jakob as his bloodlust increases. Little does Jakob know they are to become central to the Whitechapel murders.
But when a new and different source of blood becomes available to him, Jakob decides to stop Jack before he kills again. But Jack has different ideas.
The question is: Will Heaven or Hell profit?
