 A monstrous tree-logging machine, known as the Crablogger, is cutting a route through a forest in South America, but the drivers faint due to eating bad food the night before, as the kitchen at the South American restaurant they ate it at is about as hygienic as an uncleaned bathroom. This has hilarious and dangerous consequences, as the Crablogger goes out of control, en route to a major dam construction site. Stopping the Crablogger turns out to be a major headache. International Rescue have to stop the Crablogger before it destroys the dam.
