Rainsford was a man on a trip with his friend on a boat. While Whitney was sleeping, Rainsford accidentally fell off the boat and swam to the closet island he could find.
When he arrived at the island, he was surpirsed to see a large castle like home. He proceeded forward to check it out.
At this house, Rainsford met a man named Zaroff who was very well dressed and seemed nice. He welcomed Rainsford inside and gave him a change of clothes and a place to sleep.
That night, Rainsford was invited to dinner by Zaroff. As they were sitting, Zaroff started explaining how he enjoys hunting, but this explanation took an interesting turn when he told Rainsford that he hunts things with intelligence.... humans
Rainsford was disturbed and wished to leave, but Zaroff told him the only way he was allowed to is if he beat him at his own game. Rainsford was given a knife, and Zaroff has a gun he used. He sent Rainsford out into the woods with few instruction, and told him he has three days to survive and not be found.
