Nine college students staying at a friend's remote island mansion begin to fall victim to an unseen murderer over the April Fool's Day weekend, but nothing is as it seems.

When Muffy St. John (Deborah Foreman, VALLEY GIRL) invited her college friends up to her parents' secluded island home for the time of their lives, she just forgot to tell them it just might be the last time of their lives.

As soon as the kids arrive on the island, someone starts trimming the guest list... one murder at a time. What starts out as a weekend of harmless "April Fool's Day" pranks turns into a bloody battle for survival, with a few unexpected twists and turns for everyone invited—including the audience.
