The dancer is a woman with long black hair tied in a ponytail. She wears a neon purple caped shirt, dark purple leggings, blue heels, and golden jewelry. Her outfit turns red during the chorus.
The routine takes place in what seems to be a galactic field of stars. Pink lights circle and lock around, followed closely by orange lights spinning around. During the chorus, a huge white light appears in the center of the background. There are also more orange lights and the pink lights disappear. The lights follow the dancer's movements.
There is 1 Gold Move in the Classic routine: Gold Move: Make a circle with your arms.

This is also the second song where Ellie Goulding is the main artist and not a featured artist, also after Burn.
The background tracks the movements of the song and the dancer, much like in Blame. Véronique Halbrey (the creative director) refers to this by calling the dancer "a kind of galactic warrior who can just change a universe thanks to her dance moves".
