Growing up in the town of Lawless, Angelo Lagusa witnessed a tragedy: his parents and younger brother were mercilessly slaughtered by the Vanetti mafia family. Having lost everything he held dear, he abandoned both his name and his hometown, assuming the new identity of Avilio Bruno. Seven years later, Avilio finally gets his chance for revenge upon receiving a mysterious letter urging him to return to Lawless. Complying, he soon crosses paths with Nero, the son of the Vanetti don, and attempts to befriend him using the skills he has quietly honed over the years. Set during the Prohibition era, 91 Days chronicles Avilio’s dark, bloodstained path to vengeance as he systematically eliminates each of the men responsible for his family’s murder.
