At the beginning of the music video, Asteria is living in a futuristic city. One night, she witnesses an unknown light coming out of a distant tower she had begun to draw, and her eyes widen as the light forms a diamond shape on the tower's top. She continues drawing even the next day, and as she is sitting on a bench doing so, she meets a young man (Icarus) with a similarly-shaped tattoo on the back of his hand.
Asteria's attempts to find him lead her to a club (where Madeon makes a brief appearance as a DJ playing Launchpads), and she soon sees him standing in the crowd. They lock eyes momentarily before he leaves, though she manages to follow him out of the club and to a wall next to a pool of water. Embedded into the wall is a plaque with the diamond symbol she had seen on the tower; she and Icarus then press it and stand back as light travels up the wall and forms shapes above them.
Following the encounter with the symbol, Asteria and Icarus continue to decode secret messages and observe the tower. This leads to them discovering three more diamond plaques, which cause geometric cubes to float out of the tower and through the sky. One night, Asteria realizes that the positions of the plaques form a larger diamond, and she and Icarus head to its center, where they discover an escape route out of the city.
Asteria and Icarus, after leaving the city, travel across the desert and to a tower shaped like the diamond. As they open its doors, it begins to glow, and the video ends.
