Truck driver Xi Beishuo has spent years traveling for a living, deep in his heart harboring the obsession of searching for relatives after being separated from his daughter for ten years, suffering in daily isolation and torment. On a rainy night, he rescues Sanyuan, an odd-eyed white cat covered in bruises and subjected to abandonment and bullying; the man and the cat redeem each other. Driven by the realistic heavy pressure of freight inspection and car loan debts, Xi Beishuo helplessly releases Sanyuan twice. The persistent Sanyuan desperately chases her master, unfortunately misstepping and falling into a withered well in a desolate mountain, being trapped for two years. While bitterly searching for his lost daughter, Xi Beishuo guiltily treads across mountains and fields searching for the cat, finally rescuing Sanyuan through hardships and dangers, and finding his daughter. The two-way obsession is finally fulfilled, healing each other's bumpy lives.
