It’s been 10 years since Margot has stepped foot in her childhood bedroom. When she returns to help her parents move out of the house, she finds and starts reading her stepsister's old journal, stirring up the past that Margot ran away from. The play unfolds as she relives the memories of her and her step-sister, Grace, as they learn together what the end of girlhood looks like, and grow from strangers to sisters.
