Join twelve year-old twins Dipper and Mabel Pines as they explore the oddest spot on the map. Shipped off to spend the summer with their gruff Great Uncle ('Grunkle') Stan who runs the tacky tourist trap, 'Mystery Shack', the kids uncover mysterious surprises, unsurpassed silliness, and supernatural shenanigans lurking around every corner of the deceptively sleepy little town.

In this atmospheric, nerve-straining chiller, two young twins confined to an isolated country house transform their resentment towards their mother into a fatal illusion about her identity. In the heat of the summer, a lonesome house in the countryside between woods and corn fields. Nine-year-old twin brothers are waiting for their mother. When she comes home, bandaged after cosmetic surgery, nothing is like before. The children start to doubt that...

Upon learning that their mother has been lying to them for years about their allegedly deceased father, two fraternal twin brothers hit the road in order to find him.
