Chinese Take-Out (2011) on Netflix

Plot summary

Roberto lives in Buenos Aires, where he owns a hardware store and holds to a strict routine. He counts the screws in each box a supplier delivers and complains when the count is off, and he keeps an album of newspaper stories about accidents caused by carelessness. Mari visits him and wants to share his life; he keeps his distance. One day he sees a Chinese man, Jun, pushed out of a taxi, and helps him. Jun speaks no Spanish and points to an address tattooed on his arm. Roberto goes with him to the place and learns that Jun's uncle sold it years before. The police station, the Chinese embassy and a Chinese neighborhood bring no news of the man, and Roberto gives Jun a room in his house.
