Countdown plot
Tae is the best debt collector of his company. He is admired by his colleagues and feared by those he visits. He is known for collecting his debt in any way, and always has a electroshock weapon on hand. However, Tae is told by his doctor that he has liver cancer and must undergo a transplant if he is to have any chance of survival. And so he uses his professional skills to search for those who received the organs of his deceased son. The first person on his list is Cha Ha-yeon, a seductive fraud who has a laundry list of enemies. Finding Cha turns out to be easy, as she's about to be released. The deal she proposes, on the other hand, jeopardizes Tae's future, because she wants him to help her get revenge on the backstabbing crime boss who ratted her. Tae desperately tries to keep Cha, and her liver, alive until the transplant — even though Cha has other plans.
