 A completely assembled miniature oil rig on a slender barge is towed into the inlet from connecting narrow waterways.Although there is a moment of crisis when the rig strikes a gas pocket, most of this is dealt with swiftly and off-camera, and the barge, rig, and friendly drillers depart expeditiously, leaving behind a phenomenally clean environment and a wealthy Cajun family.Conflict and action for the plot is provided by the presence of a giant alligator in the area, which is believed to have eaten the pet raccoon and which is hunted in revenge.
