On a heavy rainy day, billionaire Elder Zhou accompanied his wife to a bank to shelter from the rain, but was subjected to all sorts of humiliation and chased away by the lobby manager Su Li on the grounds of ordinary attire. Judging a book by its cover, Su Li refused to verify the old man's identity, smeared the two as thieves, and even forced the security guard to search the old man. Security guard Xiao Lin was not afraid of being fired and insisted on righteously defending the old man. Elder Zhou dialed the bank president's phone call to prove that he was a top VIP client of the bank. The truth came to light, Su Li's arrogance completely collapsed, and investigations showed that she was also involved in huge economic crimes, and she was eventually arrested and sentenced. Xiao Lin, who upheld his conscience, was appreciated and promoted all the way.
