In suburban Maplewood, New Jersey, accountant Tom Reilly discovers a small, ancient creature named Grimble living on his roof—a “Watcher” who has guarded his family for generations. Initially skeptical, Tom, his wife Maggie, and teenage daughter Lena begin leaving offerings and communicating with Grimble, who warns that family tensions are weakening the house itself. Through honest conversations, shared fears, and a dramatic storm, they repair their bonds—both emotional and literal—while Grimble protects them one last time. When the family grows strong enough to stand on its own, Grimble fades away, leaving behind a home that no longer needs a guardian. A warm, humorous tale of protection, vulnerability, and letting go
