Ellie

A young woman with a tattooed arm and a backpack stands in a dimly lit space, then appears sitting on a rock in a foggy, desolate landscape playing an acoustic guitar while figures in gas masks approach in the background, followed by a scene of her playing the guitar in a sunlit, dilapidated room, a close-up of her bloodied hand on the guitar strings, and finally close-ups of her eyes and face showing signs of injury and distress.
