In "The Most Dangerous Game," we meet Zaroff and Rainsford. Rainsford is a hunter who is travelling to the Amazon in order to hunt a jaguar. However, he falls overboard and ends up in a semi-deserted island, where Zaroff lives. Zaroff is also a hunter, but he informs Rainsford that he prefers to hunt humans, as they are a lot more interesting. He tells Rainsford that if he is able to avoid being hunted for three days, he will regain his liberty.
