From the back of the game box:
Welcome to the lynch mob -- a riotous place where your own survival rests entirely on the good graces (or bad!) of your fellow man. Whether you are the marshal, a criminal , or just an honest citizen, your ability to convince others of your innocence is the only means to avoid the dreaded lynch mob.
Contents of the game include 22 citizen cards, 22 role cards and a rule booklet (or set of rule cards).
