Inspired by a murder-mystery-turned-legend surrounding a massacre near "Sam's Lake," the film follows Sam, a young woman who, every summer, returns home to the secluded lakeside cottage she grew up in, to reconnect with her traditions and memories of the past deep within an isolated forest. This year's guests are a group of hip, young urbanites, who join Sam on her annual trip. But when Sam and her childhood friend and local to the area, Jesse, take the group on an adventure to revisit the site of the murder they all come face to face with the terrifying legend of "Sam's Lake."
