The first is a classic. I've seen the others but honestly can't remember them much, except that the 4th was the silliest...
1= Los Angeles / Nakatomi Plaza, synopsis: NY cop does a ton of awesome ---steaming pile of meadow muffin--- on Xmas Eve to kill terrorists and shout Yipee Kai yay mother ---smurf---. Despite operating outside of his jurisdiction, no charges are filed.
2= Washington DC,Dulles International, synopsis: Bad ass cop returns, kills more terrorists and creates a very expense and deadly landing strip.Despite operating outside of his jurisdiction, no charges are filed.
3= New York, Synopsis : McClaine teams up with Nick Fury (code name Zeus) solving simple riddles to stop another terrorist from stealing gold in garbage trucks.
4= DC, Synopsis:US Marshall Raylen Givens tries to steal the social security fund before John McClaine buys a Macbook from the Mac kid to stop him. Uses a car to defy physics and take down da choppah. Despite operating outside of his jurisdiction, no charges are filed.
5= Russia, Synopsis: John's kid who we've never seen before is suddenly an adult spy/covert op and has the same terrible aim as his dad as they frolic in the nuclear wasteland and bond through repetitive catch phrases and bad jokes. Despite operating outside of his jurisdiction (and in this case country), no charges are filed.
