    It's a story about a teenage girl going to visit her estranged father or a surprise vacation in the middle of a school year only to get entangled in a organ harvesting fiasco, where she gets to meet a lot of ghosts her age. Because, Lake.

    To understand the movie better, these a a few stuff you have to keep in mind: 1. Teenagers are the most trusting and unsuspecting bunch of the lot.

    A) Somehow, being raised by her grandma on her mother's side, Jenny knows nothing about her dead mom, which is the most usual thing on earth. Grandma dislikes Dad, Jenny's meeting stepmom for the first time (apparently) and by the look of it she's never even heard about her, she's happy happy about it though (good on her) and she takes dubious handful of "vitamin" pills everyday her Dad prescribed from the moment she arrives. Without asking why. Without asking how he could've known her health situations without even checking her once. Because, Lake (you need strength for hiking). That hiking with Dad never happens but oh well, we'll continue taking the pills. Teenagers are trusting like that.

    B) She meets a strange child by the Lake, eyes bandaged up, never gets curious, takes her to a dilapidated building where she meets more of them, comes back to them everyday to read them poems and stories, no adults around ("make sure you're not seen by the adults, they are evil!"), never asks how they live on their own 'cause that's obviously a very normal setting of things.

    C) The situation at home gets weird, Dad locks himself in his office for hours or going over to the nearby town overnight, stepmom acting sinister though never forgetting to give her pills, she sees them arguing over some curious hush hush topic through crack of the door, Dad being generally douchy by not taking her anywhere apart from one errand to a shop and she never questions why he called her over in the first place. Vacation, yay, only she's not happy and throws a token tantrum once. Still no questions, though.

    D) Wakes up in an operating room: lost expression, learns had had an operation for a dubious "sudden adrenaline gland dysfunction": promptly back to her happy self. Doesn't matter that she was a healthy young woman all her life. What operation? What did they do to her? This doesn't look like a hospital! Why is her abdomen paining? Blegh, questions are for dummies. "I'm okay with "Operations" but can we go get an ice cream later?!"

    2. Medicine? Works sometimes. Paranormal cures? Well, work sometimes as well. Ta-Daa! We bring you Paramedical Science, guaranteed to work without a glitch through all those nooks in your body medicine and voodoo cannot reach. Got your organs and tendons turning into bones due to over-calcification? We replace the affected organ from a healthy (unwilling) donor but also make sure to carve it out in stone and throw in the middle of the lake. See, we're not sure which one works but if you pull those stone figures out of water, your new organs will turn into stone. Why? Because, Power of the Laaake! Could we have just thrown stone carvings of organs into the lake to cure you then, since that part seems to trump the other? I guess, but that wouldn't make this an interesting movie. 3. When you regain consciousness right before a multiple organ harvest from you and the bad guys are right in the next room with door ajar, don't forget to go back to your room upstairs and pull on a jeans. 'Cause you might need a drink after you've saved your own life and saved the day and pubs look down upon hospital scrub as the dress code.

    4. Octopus Medusa Lady living in the lake is a good woman, though she may be blind. Peter needs to tell her what's happening in the lake right under her nose before she comes to your rescue. Good thing she has a hotline to the cops though, they'll arrive right on cue to arrest the stepmom (for what?) while you're still searching inside the dilapidated house after killing your dad and Stepsister.

    5. It's heroic to kill your disabled stepsister who was ecstatic on learning she has a sister. Bringing the stone figures out of the lake wouldn't get back your kidney or risk your other organs now that Dad is dead but where's the fun if you don't get to kill anyone innocent?

    6. Shelly's poetry makes everything sound polished. Even repeated rants about "sensitive plants" and organs. Promise.

    All in all, I have no clue to what I just watched. Hopefully, armed with these hints you will. Good luck!
