What happened that night

Dahalia is a successful Harvard student who wakes up from a party, the victim of a brutal assault. Her life veers into a tailspin, and what's worse-- her memory of the attack has been ripped away, lieaving a cold rage in its wake. Years later, now a paralegal suffering from PTSD, she sees a video of her attack online for the first time. Now, enraged, she is about to make everyone pay.
