From the liner notes

When Som and Bank meet for the first time in the sprawling metropolis of Bangkok, they are strangers. Bank doesn't know that Som is a hooker, and Som doesn't know Bank is a drug dealer. Soon they become partners, and the drug deals they make bring them a kind of wealth they have never known. With a taste for the highlife, they plan a deal that will make them rich beyond their wildest imagination. But they soon find the price they pay, may be way too much. (Thai with English subtitles)
