Hello, Dolly! is a comedy musical based upon the Broadway production. Written and produced by Ernest Lehman, the film was directed by Gene Kelly. Starring Barbra Streisand, the movie also features Walter Matthau and Michael Crawford. The story follows matchmaker, Mrs. Dolly Levi (Streisand) as she travels to Yonkers, New York in 1890. She has been hired to find a mate for the selfish half-millionaire, Horace Vandergelder.
On her way, Dolly meets artist Ambrose Kemper who is in love with the niece of Vandergelder, Ermengarde. She promises that she can get Vandergelder's consent for him to marry her, despite him.
Vandergelder is set to court a milliner, Irene Malloy in hopes that she will marry him. When Dolly gets there, she tries to dissuade Vandergelder from courting Irene, saying she will set him up with an heiress. He agrees to meet her if he fails with Irene.
Dolly also plans on setting up the shop boys with Irene and Minnie. Meanwhile, Irene is waiting for Vandergelder. She tells Minnie that she doesn't love him but wants to find a rich man so that she doesn't have to work anymore. Minnie lets her know that the shop boys, Barnaby and Cornelius are on their way.
Cornelius pretends that he is well off and looking for a hat for a friend. When he finds that she knows Vandergelder and he is on his way, the guys hide, panicked. Later, they are able to get rid of Vandergelder and dine together.
The next day, the boys announce they are opening a hay and feed store with Minnie and Irene right across from him, demanding their back pay. Ermengarde demands what is owed to her so that she can run off with Ambrose.
Dolly explains to the spirit of her dead husband that she wants to marry Vandergelder. He proposes to Dolly after apologizing for his behavior. They decide to make Barnaby and Cornelius business partners. All is well as everyone succeeds in finding love and the lives they've always wanted.
