The video shows Zayn and Louis as they pass a joint between themselves and three other people in a car. The two performers can be heard to joke about their marijuana use.
Louis: "So here we are, leaving Peru. Joint lit. Happy days... What do you think, Zayn? About that kind of content?
Zayn: "I think it's very controversial."
Louis: "...That's just Zayn warming up there before the show. Zayn takes his job very seriously. He makes sure he goes through a two-hour intense warmup regime before every show, just to get himself in the zone. One very, very important factor to Zayn's warmup of course, is Mary Jane herself. In fact, I'm presenting it to him now for some fantastic singing."

Louis: "How is it Zayn?"
Zayn: "Nice."
