Five years ago today, Pauly and his friends celebrated his 16th birthday with a party in the old hay shed on the back of his parent's farm. Lottie disappeared that night and was never seen again, and tonight, the same group of five friends come together, for the first time since that fate filled party, to celebrate Pauly's 21st. All of their lives have changed, but the guilt and suspicion still remain. By the end of tonight they will all know the truth!
