You can picture it: the heroes of our story are trapped near an erupting volcano. They need to escape, so they start running/hop in the nearest car (with keys conveniently above the sun visor)/get in a helicopter. Somehow, in the face of a wide variety of horribleness coming from the volcano, our heroes escape by the skin of their teeth and live to tell the tale.
Ah yes, if only it were so simple.
