Laimek is an expert undercover agent. He’s on the verge of retiring in hopes of finding more time for his daughter Fakhram. Out of his duty to conceal his line of work, he’s always had to feign weakness and cowardice, even to his own daughter.

Peesaeng is an eager, confident new undercover agent looking to measure himself against Laimek. The police department decides to team the two up in order for Peesaeng to learn from his senior. The two are assigned to a drug case against a Khongdet, a wealthy man the police believe to be a drug lord.
