13 parti Completa Thirteen-year-old Sarah Hemsworth has always been mature for her age, despite her struggle with incontinence. Volunteering at a daycare is her way of proving that she's responsible, even if her condition makes her feel different from her peers. But when an inexplicable incident causes her mind and body to regress into that of a full-fledged infant, she finds herself trapped in a world where she can no longer walk, talk, or even care for herself.
With each passing day, Sarah slowly begins to age forward again-but she's forced to re-experience childhood in a way she never expected. As she progresses back toward her teenage self, she confronts hidden fears, long-buried insecurities, and the deep-rooted question of what truly defines maturity. Can she find her way back to who she was, or will she emerge from this strange journey as someone entirely new?
