NOW PLAYING Something smells at Cabbagehead Productions. Ticket sales for the indie company's slasher movies  are skyrocketing, thanks to the publicity of some real-life murders.  Remo draws the short straw to dump whoever is behind these stunts on the cutting room floor. But now it's time for the feature presentation: a terrorist bomb in New York...the White House under siege...hours of nonstop action...edge-of-your-seat thrills from the summer's biggest blockbuster: Die Down IV. Remo's problem isn't the army of extras hired to commit murder, or the truck bombs rigged to blow a Hollywood studio sky-high.  It's the Master Of Sinanju himself, Chiun, busy strutting like a tyrant and generally wreaking havoc on the set of his own top-secret movie...and smack in the middle of the greatest epic disaster of all time
