A pharmaceutical scientist returned from overseas. Her son, the CEO of a major corporation, sent his girlfriend-turned-secretary to pick her up with a rare medicine. The secretary, rushing to the airport, nearly hit a child. The scientist blocked the car, causing the medicine to shatter. The secretary and her brother then beat the scientist and destroyed her late husband's belongings. Later, at a family dinner, the scientist exposed the secretary's crimes, and the son called off the engagement. The secretary's family was arrested. She escaped prison and attempted to assassinate the scientist but was shot dead. The scientist then led the corporation to expand its empire.
