This should be a new start: one year after losing her husband, Nicole and her young adult children Justin and Jason settled in Purity Falls. First of all, the family was warmly welcomed. In particular, their rich neighbor Courtney looked very good, and soon arranged some part-time jobs for Jason to maintain family income. However, Nicole soon noticed that something was wrong, and her son came back in the suspicious night after leaving. When a young neighbor drowned in the swimming pool, things began to become dangerous. There was something wrong with the friendly Courtney, who seemed to control her son. Soon, Nicole revealed the criminal weakness of Purity Falls' healthy suburban appearance, which would threaten all their lives.
