Roberto (Rikadu Darling Ricardo Dar í n) is a silent old man, once an accident made him live in the shadow of self-remorse for the rest of his life, perhaps out of a kind of self-punishment, he did not say a word or have anything to do with anyone. The sudden visit of a cow and a Chinese named Ajun (Ignacio Huang) broke Roberto's quiet and lonely life, and Roberto took in the two uninvited guests unusually. A Jun could not speak Spanish, but he wanted to find his relatives in the Chinese community here. He had to turn to Roberto for help. Unfortunately, his compatriots and the staff of the Chinese Embassy refused to pay attention to poor Ah Jun, and it was Roberto himself who finally took him in. In this way, A Jun became a part of Roberto's life. In the process of getting along, A Jun's cheerfulness and optimism gradually helped Roberto out of the shadow in his heart, and the friendship between the two was unbreakable.
