In Japan, the college student Maiko (Kaitlyn Leeb) grieves the loss of her mother, who committed suicide two weeks ago in the notorious "suicide forest". Maiko is seeking out her body and her friends Amber (Cassi Thomson) and Terry (Dejan Loyola) decide to make a documentary about her quest as school project. Terry invites his friend Kyle (Graham Wardle) to shoot their documentary and they head to the forest. On the arrival, they meet the lonely hiker Jin (Hiro Kanagawa), who asks them to leave the dead in peace and go away and stays with them. However they decide to search the spot and soon their college mates Skylar (Tom Stevens), Brody (Jesse Wheeler) and Craig (Jeffrey Ballard) play a prank on them. While returning to their car, the trio finds a dead body and Skyler steals a Rolex from his wrist. When Jin finds what they have done, he advises that they are doomed.
"Grave Halloween" is a horror movie with careful production, gloomy cinematography and good acting. Aokigahara, also known as the Suicide Forest or Sea of Trees does exist in Japan and "lies at the northwest base of Mount Fuji and has a historic association with demons in Japanese mythology and it is a notoriously common suicide site" (see Wikipedia - "https://en.wikipedia.org/wiki/Aokigahara"). This place might be known by Japanese but is totally unknown for Westerns. Unfortunately the lead story explaining why the Japanese mother of the Western Maiko committed suicide does not work well. The explanation of her suicide is totally unreasonable. Further, if the characters were Japanese, the plot could work better; but the Japanese college shows only American students living a Japanese legend and gives the sensation of a phony plot. My vote is four.
