Every Tuesday evening, radio host Stevie Bricks encourages his audience to phone in and recount their personal tales. One particular night, he prompts them to disclose the most terrible thing they’ve ever done. High school teacher Ron Welz finds himself unable to resist the temptation to share. This turns out to be a grave error, as his confession triggers a series of wildly uncontrollable events that negatively impact his marriage and another couple’s relationship. Things take a darker turn when he starts receiving body parts in the mail, causing his life to spiral out of control. Who is behind this torment? Could it be a rebellious student, his closest friend, or even his own wife? In a city with over eight million inhabitants, everyone is a potential suspect.
