SINGAPORE SLING

A mother and a (grown) daughter live together in a secluded mansion. They spend their days playing perverse BDSM-related incestuous games in memory of their sadistic patriarch who, when he was still alive, raped his daughter when she was eleven, murdered several servants, and is now a mummified corpse with which the daughter is shown having sex. They occasionally kill their servants and bury their bodies in the garden.

When first glimpsed, the psychotic mother-daughter protagonists, half-dressed, are burying their disemboweled chauffeur in a pit they have dug in their backyard on a night with thunder and heavy rain. They lay down their shovels and drag his fresh corpse out of the bushes. He was killed in one of their usual games combining incestuous sex with murder. Shortly after this and at first unnoticed by the two women, a lovesick detective pulls his car up to the residence. He is suffering from a painful bullet wound and an equally painful yearning to track down Laura, his beloved for whom he has been searching for three years and who is known to have visited the area. It is revealed that the daughter is physically very similar to Laura.

The duo takes the detective, who suspects them to be responsible for Laura's kidnapping, into their home. As the exhausted detective is silent, the two women christen him 'Singapore Sling', after a cocktail recipe they discover in his pocket notebook. They use him as a pawn in their sexual roleplay games and their perverse entertainment, during which Singapore Sling, now a prisoner, is tied up, chained to a bed, vomited on, electrocuted, used as a sex slave, and subjected to other forms of torture and atrocities in which he is forced to participate. However, as Singapore Sling's confinement wears on he regains his strength and takes a more active role in the games. His deranged captors become concerned and alarmed when a sharp kitchen knife, belonging to the late father, goes missing and they discover Singapore Sling digging a deep hole in their backyard. They recognize that a killing is imminent.

A few days later, the daughter decides that she is fed up with having to suffer under the yoke of maternal authority, and, together with Singapore Sling, murders her mother. Singapore Sling then takes what up until now used to be the mother's role in the sexual games. However, during one of these games, a reenactment of Laura's murder, he stabs the daughter, playing Laura, with the aforementioned missing kitchen knife now attached to his penis. The daughter, while bleeding to death, shoots Singapore Sling and then he goes out to the garden and falls into the pit which he himself had recently dug. The film ends with all three characters dead.

The daughter and Singapore Sling kill the mother; Singapore Sling then murders the daughter during a sexual reenactment, and is himself shot by the dying daughter. All three end up dead.

The ending is a nihilistic spiral: each character attempts to seize control through violence and perverse ritual, but the cycle of abuse and madness consumes them all. The final tableau—with all dead—underscores the film’s bleak vision of inherited trauma and the self-destructive futility of their obsessions.
