A Killer Paradox

Wondering if the same killer is behind all the murders, Nan-gam probes Roh Bin for clues, leading to an unlikely partnership between the two.

As Nan-gam notices a clear pattern among the recent murders, he searches for Tang — unaware of another mysterious man who is doing the same.

In his search for Tang, Song Chon confronts Bin — who desperately turns to Nan-gam for help. But Tang agrees to meet with Chon, who has a proposition.

Nan-gam comes face to face with Chon, who recognizes him from the past. As Bin and Tang plan their final escape, Bin receives a menacing phone call.

The endgame to the chase leads to a final fight — and it's everyone versus Chon. In the process, Nan-gam finally learns the truth about his father.
