A wife, overwhelmed with hatred for her adulterous husband, inflicts an unspeakable wound on their son as the family heads towards horrific destruction. The film is told without any spoken dialogue.
Don't confuse it with the Argentinian movie of the same name where a train on the Buenos Aires subway system suddenly vanishes.
The series includes examples of:
- Auto Erotica: After the husband meets the mistress for dinner they have sex in his car in the parking lot. It's not very sexy, since both the son and the wife have separately found them there and are watching.
- Bloody Hilarious: Your mileage may vary as to how much of this film is disturbing and how much of it is over-the-top comedy. But the scene where the gang leader's freshly severed penis is tossed out into the street, and he cries out in despair as it is repeatedly run over by trucks, is obviously meant as gory farce.
- Bully Magnet: The son becomes this at school after the other teenagers find out about his mutilation.
- The Bus Came Back: The third act plays out after the wife, who has been completely absent during the whole middle part of the film about weird masturbation and penis transplants, returns unannounced to the home.
- Crippling Castration: The mother castrates her son to punish her husband.
- Death Glare: The wife when the husband's phone rings and she knows the mistress is calling.
- Fan Disservice: Most of the sex in this movie, really, but maybe especially when the mother is giving a handjob to her own son, while weeping in guilt/shame.
- Gory Discretion Shot: The actual castration is offscreen.
- Gratuitous English: All of the weird news stories that the man finds on the internet about penis transplants and masturbation via scraping yourself raw and bloody with a rock and such, are all in English.
- Imagine Spot: The mother, who earlier has given her son a handjob, comes into his room again for sex—but this time it's an imagine spot from the boy, who was fantasizing while he masturbates. In reality the father has killed both himself and his mother just outside.
- I'm a Humanitarian: The mother eats her son’s penis after castrating him.
- Kubrick Stare: Right after the wife cuts the son's penis off, the husband gestures for her to give him the knife. She gives him a truly scary sideways Kubrick Stare (also shown on the film's poster) and then eats her son's penis.
- Lady Drunk: The wife in the first shot of the movie, in what is also an Establishing Character Moment. She is sitting on the stairs, in a disheveled state of dress, swilling wine in the morning. She is already aware of her husband's affair.
- The Loins Sleep Tonight: The son's newly transplanted penis won't get erect when he watches porn, or when the mistress tries manual and oral stimulation, which isn't that surprising. But it does work for his mom...
- Masturbation Means Sexual Frustration:
- Early in the film the wife catches her son masturbating in his room. This is what drives her to cut off her son's penis after she's unable to cut off her husband's.
- Later in the film, both the son (after he's castrated) and the father (after he donates his penis to his son) masturbate via rubbing themselves raw and bloody with a rough stone. Supposedly this results in a climax, and in the film at least, it works.
- Match Cut: A match cut from the son opening the door to his room to the husband opening the door to the house. The latter reveals the cops, who have shown up to arrest the son for rape.
- Murder-Suicide: The father, after seeing his wife going to their son for sex again, kills her and then himself.
- Nameless Narrative: None of the characters are identified beyond their roles; the mother, father, son, etc.
- Parental Incest: This occurs between the mother and son after he is given the father’s penis.
- Phallic Weapon: About as obvious as this trope ever gets. Among the sadomasochistic ways that one can supposedly get sexual pleasure is by the friction of a knife in the body after one gets stabbed. So the mistress stabs the son in the shoulder, then, by grabbing the handle of the knife and wiggling it back and forth, stimulates the son to climax.
- Plot-Inciting Infidelity: The father’s affair is what sparks the plot.
- Raging Stiffie: Everybody in the family is surprised when the son's newly transplanted penis, which seemed nonfunctional, gets quite erect in the presence of his mom.
- Rape as Drama: The mistress is gang-raped at her place of work (a convenience store) by the group of thugs that the son has taken up with. The son fakes penetrating the mistress in order to hide his mutilation from his new friends.
- Really Gets Around: The mistress has never even met the son before, but makes an immediate sexual come-on to him as soon as he comes inside the convenience store, exposing her breasts.
- Significant Double Casting: The same actress, Lee Na-ra, plays both the wife and the mistress. This is thematically appropriate considering the film's themes of sexual obsession and incest.
- Silence Is Golden: There is no spoken dialogue in the film.
- Wall Slump: The son does this when he leaves his room and discovers his parents on the stairs, dead in a murder-suicide.
