Released from prison, and hacked off with a life of petty crime, Jim takes a new job: contract killing. But, what happens when your first hit fails? When the target has a heart attack before you can pull the trigger?

Charlotte, a keen city worker, jumps to the victim's aid in South London's busy streets. Should Jim carry out the contract and also kill Charlotte? What he shouldn't do is help her save his life.

With seven days to make ten grand, Jim starts a one-man crime spree in the heart of London. But will his budding relationship with Charlotte prove to be a help or a hindrance as he struggles to stay alive?
