Dark Night of the Soul.

Suwisal has turned 40. He's a forgetful businessman, a philanderer, indifferent to life around him, including his young and lovely fiancée. A visit to the house of his childhood triggers memories that continue to cascade when he is called for jury duty to hear the case against Piyum, a servant he seduced and abandoned 20 years before. Now a prostitute, she is on trial for murder.
