Talent manager Seung-min sees Yoon Jin-ah, a rising actress, as his one last hope to turn his life around. Just as Jin-ah is on the path to stardom, he receives a threat from her former lover and gets her sex clip on his phone. Seung-min tracks down the culprit and retrieves the tape but ends up losing his phone. He realizes there is one last evidence of the sex tape on his phone and anxiously looks for it. Yi-gyu, who found Seung-min's phone, calls Seung-min's wife and asks her to come pick it up. On the night the phone was supposed to be returned, Yi-gyu doesn't show up. Now Yi-gyu is the one holding the leverage. Seung-min tries to do everything possible to get back his phone but Yi-gyu's demands are escalating to the point of no return.
