The 1973 film "From the Mixed-Up Files of Mrs. Basil E. Frankweiler" is based on the novel of the same title by E.L. Konigsburg. The film is also known as "The Hideaways." Two children, a girl and a boy, from New Jersey run away from home and live in New York's Metropolitan Museum of Art for a week. They become curious about a statue which was donated by Mrs. Frankweiler, a wealthy widow, and visit her to find out more about the statue. The boy has saved $24.00 in coins and spends some at the museum cafeteria. The children walk around a museum "pool" and find some coins which have been thrown in it. The boy pays for a taxi ride with loose change.

Some miscellaneous files are shown. Jamie Kincaid and Claudia Kincaid are two children living in New Jersey.

Claudia has an active imagination and wishes that she was Queen Guinevere of the King Arthur legend. Jamie is her younger brother who has won $24 by playing "War", a card game with another boy. Claudia is bored with her home life and decides to run away and live in the museum. She invites Jamie to go with her. The children first ride a school bus to town and catch a commuter train to New York City.

Claudia has saved an adult train ticket which is good for two children.

The children take a bus to the museum.

The building has some carved ornaments.

The artist on the decoration, Michelangelo Buonarroti (Buonaroti), will become part of the story. Jamie pays for lunch at the museum cafeteria.

Jamie is carrying lots of change from his card winnings.

Various small change coins are shown. The museum unpacks a statue of an angel.

Claudia becomes fascinated with the statue and learns that a Mrs. Basil E. Frankweiler donated the statue to the museum and that she is a wealthy widow whose husband died eleven years before leaving her a recluse. The children visit a Macy's store which has colorful waitresses serving free samples of food.

The childeren have been sleeping in a large ornate bed exhibit and bathing in a pool.

The children walk around a pool which has statues in it. They feel some lumps with their feet and discover that coins have been thrown into the pool. They start picking up the coins to add to their funds.

The children attend "church" on Sunday morning at a religious exhibit. Museum employees move the angel statue and the children find a mark on a table. They do some library research and believe that the mark is Michelangelo's signature. They use a museum office to type a letter to the museum.

Claudia uses a Remington Rand typewriter to type the letter. They receive a reply through the postal general delivery system that the museum knows about the mark on the statue and that it does not prove that Michelangelo made the statue. The children decide to return home but first take a taxi to visit Mrs Frankweiler at her home in Essex Fells, New Jersey.

Jamie uses the rest of his money to pay the taxi driver.

The coins can barely be seen. The children knock on the door and a servant tells them to go away. They explain that they are "art experts" and are then allowed to enter. Mrs. Basil Frankweiler (Ingrid Bergman) appears.

She questions the children and tells them that they have been in the newspapers. They tell her that they are planning to return home.

Mrs. Frankweiler invites them to lunch and Claudia asks her if Michelangelo made the statue. She replies by asking Claudia if she did spend a week in the museum. Mrs. Frankweiler sends Jamie away to play cards with the servant and takes Claudia into the basement.

Mrs. Frankweiler explains that she and her husband toured the world buying art and antiques and have folders with detailed information on the antiques. She pulls out the folder for the angel statue and shows it to Claudia. It has Michelangelo's drawing of the statue.

Mrs. Frankweiler asks Claudia to keep the knowledge secret until she is 21 years old. She also tells her that she has put the folder in her will. Mrs. Frankweiler asks Claudia about what her mother might be going through with her children missing.

She admits that she regretted never having been a mother. She then has her chauffeur drive the children to their home.
