A hidden camera captures the intimate rituals of a traditional Vietnamese family, unaware of the lens watching their every move. The scent of pho wafts through the air as they share a meal, their bodies brushing against each other in a dance of familiarity. The eldest daughter, her skin glistening with sweat from cooking, excuses herself to the bathroom, only to be followed by her younger brother. The sounds of their shared secret echo through the house, a symphony of taboo and desire.
