Diana is a wild, vibrant high schooler who, along with her conservative best friend Maureen, gets up to the usual teenage misdemeanors. During their high school days, the two are involved in a Columbine-like shooting that changes their lives forever... 15 years later, despite living in suburbia with her husband and child, Diana is haunted by past memories. As the film unfolds in the past and present, Diana begins to question her seemingly perfect life and her sanity, and as her family life becomes increasingly strained, she finds normality gradually slipping away.
