After fifty-something Masumi accidentally causes her husband Dango to die during sex at a motel, she mourns with his mother Junko. Two crooked solar-panel dealers then arrive to collect a huge unpaid bill supposedly left by Dango. When Masumi cannot pay, they assault and film her in front of her son and mother-in-law, threaten to sell her abroad as a sex slave, and even force her son to violate her. The collection features 11 stories and 230 minutes of sexual humiliation involving 12 widows in their thirties through sixties, all dressed in black mourning clothes.
