Fifteen years ago, Ava Vance's once-affluent family went bankrupt overnight due to the deliberate framing by Arthur Stone, a partner of Ethan Stone Group. In her childhood, Ava Vance witnessed her father falling to his death, and her mother took her to another place to make a living. Ava Vance's mother died suddenly of heart disease due to hard work. When Ava Vance was sorting out her mother's belongings, she saw a will left by her father to take back the Vance family, and she had revenge in mind. Three years later, Ava Vance was deliberately caught by loan sharks and auctioned off in a nightclub to offer her first night. After being drugged, Ava Vance escaped and deliberately approached Julian Stone, spending one night with him before intentionally leaving. Julian Stone was late because of his own foreign language translation. Ava Vance appeared to replace the interpreter to help Julian Stone win the order. During the reception process, Ava Vance also became familiar with all his preferences and habits. This made Julian Stone suspect that Ava Vance was a sleeper agent planted by a rival company by his side, so he deliberately hired her as the manager of the new energy department. Everyone protested and resigned, but Ava Vance used her own strength to pull up the bottom department that no one was optimistic about again. Ava Vance was very careful and decisive in her work. Julian Stone tested her everywhere, deliberately exposing the company's weaknesses, which were all cleverly resolved by Ava Vance. In one confrontation after another, Julian Stone was attracted to Ava Vance and became even more confused about the woman's true purpose.
