The 3 elements of a DUDE WITH A PROBLEM story are:
1) An innocent hero who is dragged into a mess without asking for it—or even aware of how he got involved.
2) A sudden event that thrusts our innocent(s) into the world of hurt—and it comes without warning.
3) A life or death battle is at stake—and the continued existence of an individual, family, group, or society is in question.
