When her mother-in-law joins forces with her husband to pressure her into handing over her salary card, Su Wan pretends to comply. Together with her best friend, she arranges to have her monthly salary reduced to just 2,000 yuan, moves into her in-laws' home, and asks her father to take back the luxury car he gave her as a dowry.

Finally, she tears into her mama's boy husband and biased mother-in-law, wins her divorce, reclaims her property, and embarks on a new chapter in her career.
