31 October 1981. Instead of going to Azkaban Sirius Black goes on the run, determined to catch the traitorous Peter Pettigrew even as post-war violence tears through the wizarding world. Meanwhile, Remus Lupin and a handful of others work desparately to clear Sirius' name, and to find him. After all, they are not the only ones hunting Sirius. The Ministry of Magic has set the Dementors on his trail, and they have been given permission to administer the Kiss the instant they catch him. The remnants of the Death Eaters are pursuing him as well, in hopes that he will lead them to Pettigrew, whom they blame for Voldemort's defeat.
