The speaker says "Ok, on a fait une énorme erreur."

The video features a man in a dark blue t-shirt and jeans, standing in front of a bookshelf. He is speaking directly to the camera with his hands clasped. The scene transitions to show two men holding a cardboard sign that says "BLACK FRIDAY". The first man is wearing a dark blue t-shirt and jeans, and the second man is wearing a green t-shirt and jeans. The video then returns to the first man, who is now holding the "BLACK FRIDAY" sign and gesturing with his hands. The editing is fast-paced, with quick cuts between scenes. There's a graphic overlay of "BLACK FRIDAY" in the top left corner of most shots.
