Monsters all around - Orion Lukas
Frank battles left-wing "Weather Underground" terrorists who just got released from prison after serving 15 years for 16 murders.
The terrorist immediately start up a deadly campaign to bring about a social revolution and kill innocent by-standers in process. Frank takes issue with that.
Meanwhile, a mentally unstable loner called Chester starts up his own quest to battle the terrorist, killing innocent civilians along the way too.
As the story progresses Frank is forced to make temporary truce with an enemy he would rather not in order to eliminate the terrorist threat in New York that is getting greater by the day.
It all culminates in the end, when a final showdown brings all of them together. This is what Punisher is all about; a great story where things are not clearly defined as black and white. Instead, there are a lot of shades of grey in between everybody goes through.
Just like in real life.
