On a heavy rainy day, retired wealthy businessman Mr. Shen and his wife went to a bank to shelter from the rain, and were publicly driven out and humiliated by the snobbish lobby manager Li Man. Upright security guard Zhao Cheng stepped forward to help, and teller Lin Xiao bravely preserved the evidence.
