Sarah (Sarah Bolger)'s husband died, leaving behind a son and a daughter who needed Sarah to raise. With great grief and heavy economic pressure, Sarah had to struggle to support herself. To make matters worse, her son became a witness to his father's death, and the huge blow made him lose his voice, which was tantamount to adding insult to injury for Sarah. Tito (Andrew Simpson) is a local snake. Seeing that Sarah was alone and helpless, he used coercion and inducement to force Sarah to help him hide drugs. In an accident, Sarah's son discovered and destroyed the drugs, and Tito, who suffered huge losses, attempted to rape Sarah in anger. Sarah could not bear the oppression of this man, and finally decided to resist, and her counterattack soon caused a series of butterfly effects in the local area.
