The document discusses the conventions of the thriller genre. It notes that thrillers usually involve a protagonist facing off against an antagonist to solve a mystery or problem. The plots often take place in populated urban areas or exotic locations. Common thriller subgenres revolve around mystery, crime, and murder. The protagonist must overcome dangers and threats from the antagonist, who usually has the upper hand initially. Supporting characters may help the protagonist but do not defeat the antagonist.
