Greta's attitude is prickly and abrasive, masking her deeper pain and struggles, including a history of suicidal thoughts. Her grandparents are determined to help her turn her life around, but Greta meets their kindness with resistance and sarcasm.

Over time, Greta begins to form an unexpected bond with a local cook named Julie, who works at a nearby restaurant. Julie sees through Greta’s tough exterior and offers her both friendship and a job. As Greta spends more time with Julie and the humble townsfolk, she starts to open up and question her own behavior and choices. The previously rigid walls Greta built around herself start to crumble, offering glimpses of what might be a new beginning.
