Sompol Kongsuwan

A man who has been living overseas for many years returns home to find his sister and widowed mother are making a living by taking in lodgers and murdering them.

An ex-cop goes rogue and sets out to hunt down a ruthless drug cartel, even though it goes against his professional conduct. Meanwhile, the beautiful daughter of the ringleader who was killed in an internal feud has returned to Thailand from Hong Kong to take revenge on her father. She teamed up with the ex-cop to pursue the crafty villain of the local opium trade, while an anti-narcotic detective sent by the government also joins the fray.
