Ci-Ha, the enigmatic voyeur, trains his lens on an uncharted bay, where a man and woman engage in a forbidden tryst. The woman, a daring 'dam', entices the man, who proudly displays his 'thang dai bay'. The bay's calm surface belies the storm of passion brewing between them. As the sun dips below the horizon, they succumb to their desires, their bodies merging in a dance as old as time, their moans echoing across the water, a symphony of lust in the heart of Vietnam.
