Interesting quiet time travel film set in Lao.
A man can travel 50 years back to his younger self. As he once saw his mother die, he now "helps" his young self prepare a tea for his mother that will kill her, as he has "helped" many other girls.
A silent girl, a motorcycle crash, who he found when he was young, accompagnies him and his younger self.
Things start to change through his actions. Glass he breaks in the past that never was broken, now is. A girl who stays with him after searching for her mother, initially leaves for Vientiane with her girlfriend, but later becomes his captive.
The quiet girl has watched him grow old "a thousand times, but only saw him die once". Buddhism wheel of fate?
from rotten tomatoes:
An old man walks the dusty roads between his isolated farm and the nearby rural village in the company of a silent spirit whose death he witnessed fifty years earlier. For decades, the old man's regret over losing his mother to tuberculosis has bred a pathological need to ease the suffering of the terminally ill, and over the years, he has quietly euthanized several sick women. As he realizes that his spectral companion is able to transport him back in time, the old man trespasses into his own past to set in motion a plan to convince his younger self to preempt his mother's terminal suffering.
