How Long Is “Handphone”?

What happens when a scandalous item from a celebrity's past resurfaces and threatens to dampen the future of both star and management? For actress Yoon Jin-ah (Lee Se-na) and her agent, Oh Seung-min (Eom Tae-woong) , the one and only option involves re-obtaining the incriminating evidence as quickly as possible, before additional damage is done. The potential destruction wrought in this case is particularly overwhelming, given the fact that Jin-ah seeks to make a name for herself, and Seung-min wants to regain his once-prominent stature. One of Jin-ah's former lovers threatens Seung-min and places an explicit sex tape of Lee Se-na on Seung's phone. Seung locates the blackmailer, and obtains the original tape, but loses his phone in the process - meaning that one copy of the tape is still floating around, like a bomb waiting to go off. A man named Lee-gyu finds the tape and offers to return it, but suddenly recognizes the leverage that he holds and begins issuing insane demands to Seung in exchange for the safe return of the tape.
