When the president's daughter, Serika, returns to the hospital as a physician, Shiozaki views her as a threat to his ambition of taking over the facility. To secure his power, he launches a sadistic campaign to ruin Serika's reputation and force her into total submission.
Jyunichi Shiozaki uses his medical brilliance and predatory manipulation to climb the ranks of Misono General Hospital, but his schemes unravel when a betrayed subordinate exposes his misconduct to the President. Forced to resign in disgrace, Jyunichi's fate takes an unexpected turn when Serika ascends to the presidency following her father's sudden death and reinstates him as her Vice President.
