A young criminal's rapid ascent into a life of excess and violence is derailed when a routine robbery escalates into a series of cold-blooded murders. W. Sledge navigates the gritty landscape of London, balancing his illicit gains with a facade of normalcy until his own psychopathic impulses begin to dictate his actions.
