Harvard Law graduate Lily Chen, a Chinese-American criminal defense lawyer, is framed and fired by her boss Marcus for refusing to help the Klein family launder money. That same night, she saves a mysterious man named Ethan Black from three muggers in a Brooklyn alley. Ethan reveals himself as the billionaire CEO of Black Capital and proposes a contract marriage — he will restore her law license and help her get revenge, while she must help him pass his father's inheritance test and uncover the mole in his company.
