A group of camp counselors looks forward to a summer of fun and friendship.

As the counselors fight for their lives at Camp Palametto, they discover that their attacker is not just a man, he also carries a dark supernatural force. The situation grows tense as they deal with both the physical threat from the escapee and strange, eerie forces that seem to control the frightening events around them. They quickly realize that coming to Mary’s Lake was a big mistake. “Mary’s Lake is a film that pays homage to classic camp slasher movies, reflecting my deep love and nostalgia for the genre. As a first-time filmmaker, I aimed to recreate the magic that inspired me during my childhood. The film is intended to be an entertaining slasher with an unexpected twist at the end, laying the groundwork for potential sequels in the future. I hope that audiences enjoy watching Mary’s Lake as much as I enjoyed the creative process behind it.” – Mark A.
