Soon he finds himself in gangland, and deals with some tough-looking gang members by attacking them and running them off.

Unfortunately for him, a retiring cop (Robert Duvall) is on his trail, and soon things will come to blows as D-FENS heads towards Venice for his young daughter s birthday party....
