Kim Hyun-woo and Alex Hong (Lee Jung-jin) are two first-year students at Harvard Law School, both from South Korea.

Hyun-woo, who initially has a hard time adjusting to the workload, falls into the bad graces of the professor, who repeatedly humiliates or ignores him.

However, their relationship is short-lived as Soo-in's application to join OEP, an organization that provides medical care to patients in Third World countries, is accepted.

Hyun-woo is now an idealistic lawyer, refusing to take on lucrative corporate cases and only defending people he feels have no voice in the legal system.

Alex, who remained in the US after graduation, returns to Korea to take on a case for an international chemicals company, which is being accused of dumping toxic substances.
