A concerned daughter worried about the care her mother is receiving in a retirement home calls in a private investigator. He sees only one way to find out the truth: someone has to infiltrate the home undercover. He posts a vacancy and ends up with the friendly Sergio, who could use some distraction after the passing of his wife. But Sergio is not a seasoned 007 and has difficulty reporting via contemporary technologies and espionage techniques. Fortunately, he is a good listener and grows ever closer to several residents of the retirement home. His espionage mission also becomes an intimate but penetrating testimony to love and loneliness in old age. A wonderful documentary that strikes an unexpected balance between absurdism and tenderness.
