Dumb and Dumber is a 1994 American road-buddy comedy film starring Jim Carrey and Jeff Daniels. It was written and directed by the Farrelly brothers, and is their directorial debut. The film tells the story of Lloyd Christmas and Harry Dunne, two good-natured but dimwitted friends from Providence, Rhode Island who set out on a cross-country trip to Aspen, Colorado to return a briefcase full of money to its owner, only to be pursued by a group of criminals who are after the briefcase.
Lloyd Christmas (Carrey) and Harry Dunne (Daniels) are best friends and roommates living in Providence, Rhode Island who struggle at every aspect of life. Lloyd, a limousine driver, falls instantly in love with Mary Swanson (Holly), a woman he is driving to the airport. She leaves her briefcase in the terminal. Lloyd, unaware that it contains ransom money for her kidnapped husband Bobby, retrieves it and tries to return it to her, but her Aspen-bound plane has already departed.
Fired from his job, Lloyd heads back to his apartment and learns that Harry has also been fired from his job as a dog groomer. Two of Bobby's kidnappers, Joe "Mental" Mentalino (Starr) and J.P. Shay (Duffy), follow Lloyd home from the airport in pursuit of the briefcase. Mistaking the crooks for debt collectors, the duo flee the apartment and return later to find that Mental and Shay have decapitated Harry's parakeet Petey. Upset about their situation, Lloyd suggests they head to Aspen to find Mary and return the briefcase, hoping she can "plug them into the social pipeline." Initially opposed to the idea, Harry soon agrees to Lloyd's proposal and they leave the next day. Mental and Shay find out about their plans and follow them.
