Twenty-two-year-old Yang Liu sets off alone on a trip to Xinjiang to fulfill a promise she made to her father.
In the Gobi Desert, a sandstorm brings her face-to-face with a mysterious foreigner.
He has an East Asian face but speaks fluent English. He is well-equipped, yet elusive and shrouded in mystery. He rescues her from danger, but everything he does seems suspicious.
Her father's lessons echo in her ears, and memories of national security education come rushing back.
A bold thought takes shape: could he be a spy with ulterior motives?
To find evidence, she invents a lie about a watch and forces her way into his itinerary.
He sees through her act, but remembering The Kite Runner, he plays along and agrees to let her join him.
This journey begins with lies and suspicion, but will ultimately reach a destination shaped by love, identity, and sacrifice.
