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.
The nicest one can say about Sam's Lake is that it's well-shot, and that its major plot twist is genuinely surprising...if only because it makes no sense at all.
