Where’s the mask?

A man in a light-colored shirt stands in the doorway of a bus, reacting with surprise and raising his hands as a long, cylindrical object is thrust toward him from the right side of the frame. The object, held by an unseen person, moves back and forth in front of him, causing him to flinch and shift his posture repeatedly. The scene takes place inside a bus, with the interior visible, including seats, handrails, and a driver's area.
