The monk has not been home for a long time, this time to take care of his mother who is seriously ill, but she keeps glaring at him with anger. It turns out that the monk is the only son of the family, and the two of them have a knot in their hearts since the time when they left the family and had a lot of trouble. The monk tries to get closer to his mother, but she prefers to look at the wall rather than see him, and even at the moment of parting, it is still difficult to break through the gap. Before the afternoon was over, the mother passed away, and the monk's last remaining task was to dispose of her remains. However, having not been home for 20 years, the memories of the past keep coming back, and the monk's repressed emotions start to get out of control.
