In the opening sequence , one of the graphics turns into a wire frame of a beating electronic heart , which " pulls out " with each beat . As the camera zooms , the heart grows in size and " weaves " to become Duff . According to MTV News , while she doesn 't " take on " Pussy Galore , Plenty O 'Toole , Holly Goodhead , or any other Bond girl , she becomes a " Bond girl in spirit " , switching from era to era with different looks , with her hair blowing and flying around in graphic silhouettes . Instead of cutting from image to image , the shots evolve in a Bond @-@ like style " as shapes take on different forms to reveal something else " . Duff performs in silhouette , with a microphone , " where a gun would otherwise be " . In another shot , her band is a silhouette . The edition of the video is matched to the beat of the song , " zapping the view in and out , until a lull in the song , when the view travels back into her eyes , through her skin and back to her beating heart .
