On a weekend when their husbands were away, two mother-daughter pairs expected to enjoy a relaxing time together. However, a group of men suddenly appeared, thrusting emotionless, erect penises at them. The mothers, trembling in fear of the invading cocks, try to protect their daughters by offering their own bodies instead. At that moment, another mother and daughter—close friends who knew nothing of the situation—arrive at the door. In this worst possible scenario, the most horrific acts of sexual violence unfold. Daughters, mothers, friends, and friends' mothers—all become targets of relentless assault, as familial bonds, trust between friends, and human dignity are systematically destroyed. Their resistance and desperate pleas are ignored, overpowered by the relentless force of the invading cocks. One by one, everything collapses into ruin.
