As a skilled hacker, Gyeon Woomin is hired by a criminal organization to infiltrate Taeyoung Corporation and steal data. However, when the security system goes off, he's caught by no other than the CEO, Tae Beomhyun. Instead of calling the cops, Beomhyun offers him a deal that's little better than a slave contract. Left with no other choice, Woomin signs the contract and finds himself carrying out all sorts of risky and provocative errands ordered by Beomhyun.
