A girl (played by Dou Jingtong) travels to Lhasa alone, and a "seven-colored magic shrimp" that is worshipped unexpectedly changes all her plans. The girl decides to drive across half of China alone to return the magic shrimp to the sea. Along the way, she encounters people and things of all kinds, and memories, dreams and hallucinations appear in front of her intermittently. In the end, the shrimp-releasing journey ends in an unexpected way, and the girl arrives at the most secret world in her heart.
