Mountaineer Shiga made a promise to his best friend following his tragic death in the Himalayas - now 12 years later he is called upon to honor that promise. When 15-year-old student Megumi fails to arrive home from school her mother calls on her dead husband's best friend for help. Shiga abandons his mountain refuge and enters the city to look for the girl - and with the police investigation at a standstill, Shiga has to go it alone.
