*SPOILERS* Plot
Besides the fact that from reading this board it seems nearly unanimous the police in this film rank as stupidest ever
Wondering if anyone can post a more detailed plot summary of this film
Wondering if you're lazy or have very limited Internet skills?
Found five highly-detailed plot summaries for this film within 20 seconds, so why should anyone take the time to type one out just for you, or provide links you can get in less time then writing your post?
FYI - Wikipedia always offers a detailed synopsis, so does AllMovie, so does... and, hey! there's even a detailed synopsis of this film already on IMDb, all with major spoilers, but since your post comes with a pre-spoiler alert...
Sure, I could have provided the links in the same time it took me to write this reply, but that would have countered my point.
Ignorance is bliss... 'til it posts on the Internet, then, it's annoying.
