The Forest of Love (2019)

Joe Murata (Kippei Shiina) sits in a restaurant as the misdeeds of a serial killer are reported on TV. Murata carries a yearbook from a girls' school, with numerous photos crossed out. He tells the waiter he's a screenwriter and asks if he knows what it's like to kill someone. Two young men, Jay and Fukami, meet another young man, Shin, and take him to the vacant warehouse where they're living.

Jay says he wants to make movies to explore all kinds of criminal behavior legally. When Shin reveals he's a virgin, Jay takes him to meet a promiscuous girl. The girl, Taeko, refuses Shin but introduces him to her high school classmate, Mitsuko, a shut-in with well-off but strict parents. Mitsuko says she is also a virgin but isn't interested in Shin. Taeko argues she should "make some scars and move on". When Mitsuko and Taeko were in high school, their class worked on a production of Romeo and Juliet for the school festival. Mitsuko was to play Juliet, with Eiko as Romeo. With little experience with boys at their all-girls school, they explore sexuality and romance among themselves. Eiko is killed in a car accident, and the play is cancelled. Five of the girls decide to take sleep medication and stand on the edge of the school roof. Taeko vows to become a "slut" if she survives. Mitsuko sees a vision of Eiko and does not fall, while the others fall. Taeko lands on a parked car and is left with a limp and a scar. She gets "Romeo" tattooed on the scar. In the present, Mitsuko receives a call from Murata, who claims she had lent him 50 yen years ago. He claims he is now successful and wants to return the money. They meet at a park, where Murata arrives in a sports car and expresses attraction to her. Shin, Jay, and Fukami watch and record this. Mitsuko watches the video with Taeko and says she recognizes Murata as a con artist who had claimed to want to marry her sister. Taeko recalls sleeping with Murata and seeing him seduce her mother. The young men obtain a filming crew and begin making a film about Murata's cons, with Shin as Murata. Meanwhile, Murata seduces Mitsuko, her younger sister, Ami, and Taeko. He stages a concert, where many of his former victims show up to compete for his affections. The three filmmakers, Mitsuko, and Taeko meet up with him afterwards. Mitsuko reveals she is sleeping with Murata and shows them the burns and scars he left on her. Murata lifts Taeko's shirt to reveal more of the same. Murata says he can help with their movie, as he is wealthy. Fukami quits and leaves. The others accept. It is revealed Murata has no money. The film crew quits, leaving Jay, Shin, Taeko, and Mitsuko on the project. Murata takes over the film and revels in cruelty to them. Mitsuko says she is pregnant with his child. Murata takes them to a country house and coaches Mitsuko in a scene where she strangles Jay. Jay dies. Murata convinces them to destroy and dump Jay's remains in the lake. Taeko jumps from the boat to escape but is killed by an unknown gunman. They go to Mitsuko's home, where Murata uses Mitsuko's involvement in Jay's death to blackmail her parents, torturing them on camera. He tells them to get a relative to fund the film. Ami enjoys his torture of her parents and Mitsuko. Mitsuko attempts suicide after watching Ami have sex with Murata. Murata, Ami, and Shin decide "tomorrow will be Mitsuko's death scene". Mitsuko and Ami go dress shopping for the scene, and Ami thwarts her attempt to escape. Mitsuko has a miscarriage and is hospitalized. The relative discovers the film company is a sham and arrives to demand his money back. Inside the house, he encounters Mitsuko's drunk, raving parents. Murata and Shin return to find Mitsuko's father has hung himself. Her mother and relative lie on the floor with a bloody knife nearby. Ami returns home to find Murata and Shin have dismembered the relative. She decapitates her father and discovers her mother is alive. At her mother's request, Ami kills her. Murata, Shin, and Ami take Mitsuko to a forest, where she agrees to be killed. She explains she had not taken the sleep medication and had hoped Taeko would die, that she had sex with her friends' boyfriends as well as Ami's. She had known Murata was a con artist and Shin was a killer but hoped they would kill Ami, her parents, and Taeko. Shin shoots Ami and Mitsuko, then gives the gun to Murata and orders him to kill Ami, who is begging Murata for her life. Shin berates Murata then kills Ami himself. He reveals himself to be the serial killer reported on the news. They fight, and Murata escapes and waves down a car driven by a woman who resembles Eiko. When asked where she is heading, she answers, "To hell. " Shin takes the car they came in and gives a lift to a woman with car troubles. He sees Eiko by the side of the road, stops, and runs into the forest after her. The on-screen text states that those behind the murders that inspired the film were caught in 2002 and sentenced to life imprisonment.
