A group of friends who are in their thirties who have been inseparable from high school have planned a unique "end of summer carnival" when summer is about to end.With the friendship accumulated by the years and the enthusiasm of youth that has not yet dissipated, they tried to use a bold and unrestrained gathering to draw the last stroke of the past summer at the time of seasonal change.This is not only an impulse indulgence, but also their affectionate look back at the passing time and a brief escape from the bondage of reality.
