The document outlines a proposed music video treatment for the song "How to Be a Heartbreaker" by Marina and the Diamonds. It would include various storylines of the artist with a love interest, intercut with performance footage. Key elements include using stop motion for lyrics about "rules", a party scene to match the tempo, and jumping between intimate moments and the stage performance to follow the story of falling in love but not wanting to get hurt. The overall treatment focuses on visually bringing the lyrics and themes of love, danger, and heartbreak to life.
