Jahan and Yasmine are the'good' main characters. And Kris (Rain Man) would be the 'bad' main character.
Jahan is chillin in their apartment (she has already gotten her heart taken). Yasmine walks in and Jahan realizes her heart has also been taken. Jahan and Yasmine both agree who did it. Jahan and Yasmine are going after a wealthy tycoon (Kris) who is stealing hearts. Jahan and Yasmine gather other heartless people to go after the tycoon. Jahan and Yasmine and the army go to war with Kris's army. The city streets are becoming a battleground. Jahan and Yasmine fight their way through Kris's army and up through the building to Kris. Kris transforms into a monster of darkness (that steals hearts, of course). They battle him and in the end stabs him in the heart. Every heartless person gets their hearts back.
- The Heartless People have a dark empty hole in place of their heart
- Heartless don't act different then humans in the sense that they do daily human acts but they seem emotionless/heartless
