From publisher blurb: Our other staple of the convention season last year was Posse Comitatus. You and your group have just finished rounding up some bandits and are enjoying a relaxing moment in the city of Alcatraz. Your tranquility is disrupted with a loud noise and you quickly discover that there is a jail break in progress! This adventure setting was designed for 5th Edition rules for the Filbar Campaign for six, fourth level adventurers and DM.
