Then Isla discovers something unexpected: a handwritten Route 66 itinerary hidden among her mother’s belongings — a carefully planned trail stretching west across forgotten diners, neon motels, and empty highways.
Desperate to keep the family from falling apart, Isla joins her father and brother on a chaotic cross-country road trip that quickly becomes more than a search for answers. As the miles grow longer and old wounds rise to the surface, they begin to uncover the quiet truths their mother left behind — and the painful reasons she needed to leave.
Tender, cinematic, and deeply human, The Summer Mom Disappeared is a story about grief, survival, and the fragile ways families try to find each other again when everything familiar has been left behind.
