Fresh Perch

A man in a black t-shirt and cap walks through a supermarket aisle, then turns and is confronted by another man in a black shirt who grabs him from behind; the man being grabbed struggles and turns to face his attacker, who then appears to be pushed or falls backward, causing the camera to fall and show the floor. The scene takes place in a brightly lit supermarket with shelves of products and other shoppers visible in the background.
