Wu Dongjiu (played by Yoo Deok-hwan) was born chubby and very cute, but in his heart, he longed to be a beautiful and sexy woman like Madonna. The persistent Wu Dongjiu insisted on this dream that seemed to be impossible to achieve forever, and finally, he decided to undergo sex reassignment surgery.

However, wrestling training is far more difficult and hard than Wu Dongjiu imagined. Can he, who has a gentle and non-aggressive personality, become a strong wrestler and win the competition?
