It is 1967 at the Metropolitan Museum of Art (The Met) in New York City. Mrs. Basil E. Frankweiler is a collector of fine art, facts, figures, and secrets. She narrates the action of ArtsPower’s exciting musical play through a letter she is writing to her lawyer, whom she calls Saxonberg. 

After she learns about the adventures of Claudia and Jamie Kincaid, two children who have run away from home to live at The Met for a few days, Mrs. Frankweiler needs her lawyer to change her last will and testament. Among her many files, she will now include the story of how Claudia and Jamie run away, hide out and sleep over at The Met, investigate whether a statue called Angel was carved by Michelangelo, and, in the end, become a terrific sister and brother team. 

ArtsPower's fast-paced musical is accompanied by a comprehensive Activity Guides that includes interviews with two members of the cast, an art history activity, information about the Renaissance, learning to act in a scene from the show, and playwriting.

The show's themes focus on family, friendship, self-discovery, and adventure.
