Il prigioniero (2019)

A nondescript, law-abiding individual - a real "gray man" - goes out one morning to buy fish at the market, but crosses paths with an excitable mob of people he doesn't know. They think he's a thief and chase him down the street, until he shakes them off by hiding in a basement. A nasty and none too bright cop finds him there, roughs him up and searches him. Once he realizes he's innocent, the cop leaves, after ordering him not to move from the spot till he returns. The nondescript former suspect obeys the policeman to the letter, and waits for days, hands up, not moving a muscle, for his Messiah to come back for him.
