In the Taiwanese countryside, a high school senior, Shuan, is passionate about playing guitar. One summer day, his parents argue heatedly about money. Pretending to attend the study group, Shuan escaped his household chores and went to the city to hang out with his bandmates. Later that day, a typhoon hit, bringing strong winds and heavy rain. Meanwhile, Shuan’s mother had not yet returned home, and his young sister was nowhere to be found.
