toby: gory story idea:
half-ton Mexican man gets hired to transport $800,000 worth of heroin into the united states within his "natural saddlebags". he doesn't shower for a month prior to the journey so he's absolutely disgusting and no border guards want to search him. he gets wheeled through "to seek treatment in the US", travelling with an "aide" who is actually a hired assistant of the drug traffickers. lots of gross shots of bugs crawling out of his flab, and stink lines.
when he arrives in the US, there's an extended disgusting border scene, but he gets through. he gets to the traffickers' place and they put on gas masks and start digging out the packets. when it's all said and done...ONE IS MISSING!
then comes the climax/twist.
