John McClane arrives in Los Angeles, gets chauffeured to the Nakatomi Plaza, escapes as the building is taken hostage, beats up and kills several henchmen, forms a reassuring bond over the radio with Sgt Al Powell, saves the day AND comes up with a new catchphrase to repeat when the same shit happens to him another four times.
A SWAT team attempts to storm the Nakatomi Plaza but are all easily killed by rockets, this prompts McClane to use a bag of C-4 to blow up an entire floor of the building, killing the goons responsible. This probably takes place at around the 10pm mark but, really, who’s checking their watch?
If It Had Taken A Year:
It would be the longest hostage negotiation in history, with frequently ordered pizza and loo breaks. Gruber and his men would no doubt eventually become friends with their hostages and, when it was all over, the FBI would find a skeleton wearing a white vest up on the roof.
