Jeffrey 'The Dude' Lebowski, a Los Angeles slacker who only wants to bowl and drink White Russians, is mistaken for another Jeffrey Lebowski, a wheelchair-bound millionaire, and finds himself dragged into a strange series of events involving nihilists, adult film producers, ferrets, errant toes, and large sums of money.
