Josh Bowman is a twenty-year-old son of his time, the current one, which means he is a bum, one of those young people who spends the day playing console without doing anything lying on the couch.
He has a girlfriend, who is kidnapped. The police can not do anything, so for the first time in his life Josh has to move and do more than spend the day lying down.
He is going to have to make way for a London that remains hidden to people like him, a sinister London that is very much like that of the time of Jack The Ripper, with neighborhoods in which no one else alien to them.
In that environment Josh is going to transform. He has to, because that is the only way he has to free his girlfriend, whose life is most endangered every hour that passes hijacked in that area of London.
