While delivering credits on her speedy hover board from door to door in a future where technology has advanced but society has fallen to ruin, T finds an interesting pair of headphones. They allow her to connect to Music, an angel, or menace on her shoulder - her likeness formed by T's imagination.
When a team of suits point their crosshairs at T to get the headphones back, her and Music must evade them and find out why they're so important.
