Virginia is proud that she belongs to a clique. The best students at a private school. But before her 18th birthday, a gruesome set of murders take place and her friends are the ones who are falling prey. Could it be her? She suffers from blackouts due to a freak accident one year earlier. We soon learn the truth behind her accident and what is going on.
Unfortunately the movie Happy Birthday to Me is not yet available on HBO Max.
