The video appears to be taken from inside a crowded stadium during a concert. The camera is initially pointed down at the crowd, then pans upwards, revealing the packed stadium and a tall, dark structure on one side. The video then transitions to a stage where a performer, possibly FKA Twigs, is standing in the spotlight. She is wearing an elaborate outfit with what looks like large wings, then later a black outfit with her hair in a ponytail. The stage is surrounded by dark structures, and there is fog or smoke present.
