A hit man named Kai flies into Bangkok, gets a gun, and orders a cab. He offers a professional female driver big money to be his all-night driver. But when she realizes Kai is committing brutal murders at each stop, it's too late to walk away. Meanwhile, an offbeat police detective races to decode the string of slayings before more blood is spilled.
