Chasing Ashes

Following the events of 'Entangled in a Spider's Web', after Sungmin and Ryeowook are sent into hiding, Kyuhyun and Yesung begin to kidnap and torture officers from the 18th Precinct, giving the police an ultimatum; every few days they will kill a new officer until Sungmin and Ryeowook are returned to them. Now, Donghae, Siwon, Seunghyun, and Changmin must race against the clock to track down the criminals before they become victims themselves.
