Charlie misses her flight. Lucy arrives in Bangkok alone and bewildered. Lucy spots a monk in the What Pho monastery who attracts her.
Charlie arrives that evening. The next day Charlie wants to have a soapy massage. Lucy is not interested. A man comes out of a cubicle with a pretty Thai girl. Lucy realises he is the monk she had seen at the monastery. The monk's name is Nat.

To disguise his identity, Nat is either masked, or the room is in darkness. As Lucy gets more confident she wants to have Nat all to herself. She resents Chimlin's presence.
In her search for Lucys Charlie is helped by Beam who is a journalist friend.
