After bowler Roy Munson swindles the wrong crowd and is left with a hook for a hand, he settles into impoverished obscurity. That is, until he uncovers the next big thing: an Amish kid named Ishmael. So, the corrupt and the hopelessly naive hit the circuit intent on settling an old score with Big Ern.
When "The Dude" Lebowski is mistaken for a millionaire Lebowski, two thugs urinate on his rug to coerce him into paying a debt he knows nothing about. While attempting to gain recompense for the ruined rug from his wealthy counterpart, he accepts a one-time job with high pay-off. He enlists the help of his bowling buddy, Walter, a gun-toting Jewish-convert with anger issues. Deception leads to more trouble, and it soon seems that everyone from porn empire tycoons to nihilists want something from The Dude.
