Hugo, a successful 25-year-old guitarist, returns to his late Grandma Rosemary’s cottage, feeling remorseful for how he treated her. In the humble house, he reflects on his past actions, remembering how he mocked her job as a street sweeper and resented her financial limitations. Despite Rosemary’s efforts, Hugo rejected her gestures and berated her in front of friends.

Upon her death, Hugo inherits an urn with Rosemary’s ashes, initially dismissing it as inconvenient. As he explores her house, he discovers a locket in the urn, prompting him to read her diary. The diary reveals Rosemary’s past, including a deep but unfulfilled love with a childhood friend, Henry.
