Fang Yuan, a second-year graduate student specializing in financial law, discovers that 200,000 yuan has been fraudulently charged to his credit card overseas. Instead of panicking, he immediately reports the incident and meticulously collects and preserves evidence throughout the process. Armed with his solid legal knowledge, he firmly pushes back against the bank's evasive tactics and regulatory violations, ultimately securing 400,000 yuan in compensation. Later, while dining out, he sees through a restaurant's extortion scheme and defends his rights through legal means. He also exposes his classmate Liu Qiang's hypocritical nature, revealing how he takes credit for others' achievements and refuses to repay his debts.
