A dog chewing a hole in the floor.

The ad opens with a dog chewing on a wooden plank, creating a hole in a wooden floor. A man in a robe is startled. The dog then jumps through the hole with the plank in its mouth. The man chases after the dog, who is running outside. The man, still in his robe, runs into a Castorama store. Inside the store, a sales associate holds up a plank, and the man, holding the dog, asks if he needs new flooring. The ad ends with the Castorama logo and a call to action.
