Lee Inwoo will do anything to for his family - no matter the consequences. After learning about a potential plot to leak sensitive information, Inwoo travels back to Korea to track his brother’s last known location. His search leads him to Dr. Kang Dowoon, a doctor with connections Inwoo is dying to get his hands on. But, as the two grow closer, the both of them fall deeper and deeper into a tangled web of deceit and mystery that neither of them could have anticipated... Chasing this rainbow is bound to lead to something much less pleasant than a pot of gold.
