A man burdened with massive debt is captured by a loan company run by Queen Mona after missing his repayment deadline, and is bound and restrained. Queen Mona forces him to choose between repaying his debt or becoming a human pet. The man chooses the path of a pet. Once transformed into livestock, he is used solely as a tool to provide pleasure for Queen Mona, enduring increasingly harsh treatment. Yet, over time, he begins to find pleasure within the pain and grows dependent on her. Meanwhile, redundant employees at the loan company are also given the ultimatum—termination or becoming a pet—and some choose the latter. However, Queen Mona believes one pet is enough, so she pits the two men against each other in a brutal, survival-style game. In their desperation, the men form twisted bonds and fight each other for their very lives.
