When a nameless, struggling actor in 1970s New York gets the call that an enigmatic director wants him for an art film set in the Amazon, he doesn't hesitate: He flies to South America, no questions asked. He quickly realizes he's made a mistake. He's replacing another actor who quit after seeing the script - a script the director now claims doesn't exist. The movie is over budget. The production team seems headed for a breakdown. The air is so wet that the celluloid film disintegrates.
