Plot Summary

Members of a cult modelled on Aum Shinrikyo sabotage a city's water supply, then commit mass suicide near the shores of a lake. Family members (the credited cast minus Asano) of the perpetrators meet at the lake to observe the anniviersary of their loved ones' deaths. While there their car is stolen. They meet a former member of the cult who had trained for the water sabotage attack but defected last minute. He leads them to the cabin he's currently holed up in, where he and the deceased cult members had trained for the attack, and they pass the night reminiscing about those they'd known and lost, shown cinematically through improvised dialogues and flashbacks. Sakata, the surviving cult and last to see most of the departed alive, and Atsushi (Arata) interrogate one another about Yûko (played by actress/model Ryo), Atsushi's sister whom Sakata had asked to run away him the night before the attack, whom (it appears) neither really knew.
