AFTER THE SNOWMELT is a coming-of-age tale exploring teenagers' first encounter with profound loss. At the age of 20, filmmaker Yi-Shan's best friends, Chun and Yueh, were trapped in a Nepal cave for 47 days due to unseasonal snowfall. Chun died three days before the rescue, leaving Yueh as the sole survivor. Yueh returns and reveals a promise made between him and Chun: the survivor must share their story. To honor Chun's last wish, Yi-Shan takes up the camera, accompanies Yueh to the mountains, and retraces Chun’s footsteps in Nepal. Gradually, her journey overlaps with Chun’s, blurring the boundary between past and present, and arrives at the same destination. When Yi-Shan reaches the cave, she must confront the future alone.
