Nobody knows the city like Blade. He lives on his own, by his wits - you have to when you're on the run from your past. Blade is practically invisible, until one day when he gets jumped by a gang and finds himself being pursued by a bunch of thugs. Even worse, he's unintentionally picked up a couple of followers: sixteen-year-old Becky and her daughter, Jaz. Before he knows it, Blade is leading the two girls on a chase through the streets of London, and he'll need to find a way to outsmart the people after them in order to make it out alive.
