Her carefully controlled world begins to shift when she reluctantly takes a job teaching a children's math class, where she forms an unexpected bond with a perceptive young student, portrayed by Bailee Madison. As Mona navigates this new connection and the awkward advances of a charming hardware store owner, Chris Messina, she must also confront the lingering emotional shadow of her father's mysterious illness, with J.K. Simmons as her distant, ailing parent. This poignant drama from director Marilyn Agrelo explores the invisible signs of love, loss, and human connection that defy simple calculation, charting one woman's delicate journey from isolation back into the messy, beautiful realm of the heart.
