Three friends are asked to be bridesmaids at a wedding of a woman they used to ridicule back in high school.

On the day of her wedding, as Selena Jackson comes to terms with the long-lost love she's never quite gotten over, many of her guests, including her best friends and her own mother, also struggle with past loves, past regrets and past mistakes.

A group of friends at a bachelorette party are stalked, tortured and murdered by a masked figure, who forces them to face a long-buried secret.
