Chateau Dankworth is a bounty hunter who crosses paths with Song Ryang-ha, a professional hitman, during one of her jobs. Rather than fight her, he starts shadowing her and trading valuable information for the promise of a date. Wary and unwilling to let him in, Chateau keeps her distance even as Ryang-ha makes himself impossible to shake, a pursuit that turns more dangerous as their separate pasts begin pulling them toward the same enemies.
