The Mule

A naive man smuggles drugs from Thailand back to Australia inside of himself. When he's caught at customs, Ray refuses to "release" the evidence or admit he's even carrying any drugs, so he's taken into custody until he talks or defecates.
 Ray Jenkins is a nice, kind guy who's just a little too naive for his own good. When Ray's longtime buddy, Gavin, pitches him the idea of smuggling drugs for some quick cash, Ray reluctantly agrees to do it, swallows quite a few bags of narcotics and attempts to fly back home to Australia, waltz through customs and collect his earnings. Trouble is, Ray loses his cool and gets nabbed by the Australian Federal Police before he can make it out the door. When Ray refuses to come clean and tell the cops what's floating around in his belly, they make it so he has to by confining Ray to a hotel room and monitoring him around the clock until he can't bear to hold in his secret anymore.
