A Samoyed named Icarus left home in a huff after being shaved bald, and from then on plunged into the depths of life as a stray. She endured hunger, a broken leg, love, and betrayal. She gave birth to her puppies beneath a bridge, suffered the loss of a daughter, and raised Lasi and Sailor alone. In the winter of her fate, her daughter-in-law and young grandchild died one after another, and she dragged her broken body toward the end of her life. Just then, an animal shelter found her grown-up young master, Shen Xingye, through the dog tag still hanging around her neck. In her final moments, the boy knelt beneath the bridge and laid his palm on her head. At last, Icarus flew back to the sun.
