Complete Monster: The Party Crasher is introduced calling the police to cheerfully inform them of his intent to commit a murder at a nightclub before invading it, gunning a man down and escaping. Targeting petty criminals and drug dealers, the Party Crasher initially claims he is doing police's work for them, but his sadistic demeanor and cruelty reveals this to be a lie, with carnage and fame his real goal. Murdering a prostitute soon after, the Party Crasher takes a gun dealer hostage and later executes him before escaping and attempts to fire on an innocent crowd, killing at least one man. When police lieutenant John Moss confronts him, he reveals the Party Crasher murdered a 4-year-old-girl in the past, to which the Party Crasher only laughs that one sacrifices pawns. Taking Moss's girlfriend hostage, the Party Crasher holds her on the theater rooftop to lure Moss to him, with the intent of murdering them both, along with Moss's partner, actor Nick Lang.
Nick: C'mon John. Look, my character kills this guy. It's probably an innocent by-stander. I just want to know what that's like.
John: You can't. Not by asking someone.
Nick: Will you open up? I just want to know what it feels like to be inside your skin.
John:I don't want you inside my skin, you understand? It's private! What's in there belongs to me! You're not gonna learn what it means to be a cop by eating hot dogs and picking your teeth and asking stupid questions. We live this job. It's something we are, not something we do! Every time a cop walks up to a car and has to give a speeding ticket, he know he may have to kill someone or be killed himself. That's not something you step into by strapping on a rubber gun and riding around all day. You get to go back to your million dollar beach house and your bimbos and your blow jobs and you get 17 takes to get it right. We get one take. It lasts our whole lives. We mess it up and we're dead.
Nick: (takes out a tape recorder) Fuck, that was great! John, look, can you just say that one more time for me, please?
Harsher in Hindsight: When John's daughter admits she prefers Mel Gibson to Nick Lang, John proceeds to rile up Nick and telling him, he (John) loves Mel Gibson. Look at how James Woods turned out, and that can be very uncomfortable to hear/watch...
