As the snow gently falls outside, the festive atmosphere quickly turns dark when they start receiving unsettling and mysterious phone calls. As the night progresses, the messages become increasingly disturbing, revealing past secrets that none of them expected to confront.
The girls, led by the charismatic and determined Kelli, strive to stay calm and enjoy the celebration.

With a tense and chilling atmosphere, the sorority transforms into a maze of despair and distrust. Paranoia grips the group as they try to unravel who might be responsible for the horrific crimes. As hours pass and the number of victims rises, the struggle for survival intensifies, leading to a climax that will unveil dark family secrets and test the limits of loyalty and love.
