In the story, when an overworked mother and her teenage daughter magically swap bodies, they have just one day to put things right again before the mom's wedding.

[7] Blickenstaff and Hunton then appeared at the Cleveland Playhouse from April 15 to May 20[8][9] and at the Alley Theatre, Houston, Texas, from June 2 to July 2.

[14] According to Entertainment Weekly, "presently there are plans to transfer the show to Broadway, the door is also now wide open for licensing for professional, regional, and amateur productions around the country".

[15] The musical will have its UK premiere at HOME, Manchester from 27 November to 31 December 2025, directed by Andy Fickman and produced by Paul Taylor-Mills.

[16] The musical opens with Ellie Blake telling the audience about the worst 24 hours of her life ("Just One Day").

Katherine reveals that she sold the hourglass's twin, a present from her late husband, to help pay for her catering business.

She relies on Katherine's assistant, Torrey, to answer most of the questions and fabricates a story of how she operates her business ("What You Got").

Katherine meets Adam and her teenage body's chemistry makes her feel attracted to him ("Oh, Biology").

Mike arrives at the house to get ready for the rehearsal dinner and is interviewed with Ellie about their beautiful flowers.

After Ellie picks up Fletcher from his school, she discovers that the pawn shop her mom sold the hourglass to has closed.

Gretchen and Hannah feel betrayed by "Ellie" and Adam refuses to add the hourglass as it wouldn't be fair to the other competitors.

The wedding guests discover Fletcher has run away and wonder what tomorrow will bring ("Just One Day (Reprise)").

All of the wedding guests band together to find Fletcher while Ellie, Katherine, and Torrey lament to the audience how wrong this day has gone ("Not Myself Today").

The officers jump to the worst possible conclusions, worrying the entire family ("Bring My Baby (Brother) Home").

"Katherine" tells Adam that the hourglass was a gift from Ellie's late father and he decides to put it on the list, seeing how important it is to her.

Ellie convinces Torrey to return to work and Mike replaces the wedding cake with seven-layer bars.

This leads to a physical altercation over the hourglass with Katherine breaking Savannah's nose and stealing it back ("No More Fear").

Katherine and Ellie grab hold of the hourglass and affirm their love for each other, switching back to their original bodies.
