In the Salinas river in Cali , two workers named George and Lennie travel to a ranch to go to work since Lennie accidentally grabbed a girl by her dress.
Lennie and George are actually good friends but due to Lennies mental disability they often disagree
The bosses son Curly hates Lennie immediately and discriminates against him. And Curly's wife causes mischief by seeking the mens attention . But they do make friends with the ranchers , especially Candy.
Slim gave Lennie a puppy and he was in the barn tending it when Curly's wife enters the barn and they talk . He grabs her hair without knowing it because he likes soft things and she tries pulling away and he snaps her neck.
George gave Lennie specific instructions that if anything bad ever happens to hide near the river . George finds him there.
George has to shoot Lennie before Curley finds him .
