Suspension of Disbelief: AND SOON THE DARKNESS
If you are a cute chick or a pair of cuties it is probably best to avoid bike tourism in lawless border regions of South America. If you have been kidnapped to be sold into sex slavery and you somehow manage to turn the tables on your abductor by whacking him in the head with a plank remember to keep on whacking until there are no signs of consciousness. Better yet keep on whacking until there aren't any vital signs at all. This will prevent your abductor from making a comeback. Also, if you are pointing a pistol at a corrupt sheriff it is probably never a good idea to turn your back on him no matter what he says.
