Psychos in Love

Joe, a bartender, and Kate, a manicurist, meet while both searching for a long-term partner. They immediately reveal they are murderers and find common ground in their brutal pasts. The revelation leads to an unlikely bond over their mutual hatred of grapes.

Before meeting Kate, Joe had murdered many women after bringing them to his home. His pattern is established as a chilling routine of luring victims and killing them. This history hangs over the couple as they grow closer.

Kate has exclusively killed women, a detail she shares with Joe to emphasize their shared darkness. She confirms that her victims are always female, highlighting a disturbing parallel with Joe's crimes. This realization cements their bond.

During a house visit to a male mechanic, Kate is assaulted, but she fights back. She stabs the attacker with a nail file and then bludgeons him to death with a rock. The act marks another escalation in her murderous acts.

Susan, a topless dancer, auditions for a job at Joe and Kate's home, only to be stabbed to death by Joe. He decapitates her and uses her head as a decorative centerpiece in the kitchen. The brutality underscores their growing psychopathy.

As their relationship deepens, Kate suggests that they commit a murder together. Joe agrees, setting the stage for shared, coordinated violence. The couple's bond now centers on carrying out crimes as a team.

Joe brings Nikki, a dancer from the bar, to the house. He stabs her several times, but she initially does not die. After she recovers, he clobbers her with a frying pan and finally shoots her with a shotgun when she becomes dangerous again.

Kate suggests stopping the murder spree due to boredom, deciding they will marry first and then dismember Nikki. This marks a shift from random killing to a murderous partnership with a long-term plan. The plot twist intensifies the couple's dynamic.

The couple marries and honeymoon in Chicago. During their trip, they encounter a female prostitute at an oldies bar, and Joe, never having murdered a prostitute before, stabs her to death in the shower. The murder expands their repertoire and fantasy further.

Following their honeymoon, both Joe and Kate resume their murderous urges and resume killing for pleasure. The thrill of violence remains a driving force in their relationship. Their bond remains strong despite periodic friction.

Kate grows jealous of Joe's encounters with other women and begins to doubt the enjoyment of murder itself. She contemplates how the thrill has faded and questions the sustainability of their relationship. The couple's dynamics start to fracture.

To rekindle their excitement, they buy a VCR and rent numerous horror videos, including the Friday the 13th and Halloween series. They search for voyeuristic thrill and renewed inspiration through cinema. This marks a shift toward consumption rather than immediate violence.

Their kitchen sink becomes clogged with the entrails of their victims, prompting a call to Herman, a neighborhood plumber who is revealed to be a cannibal. The encounter triggers blackmail and a threat to cook them with grape sauce if they refuse to supply corpses. The tension escalates into another brutal confrontation.

Joe turns off the lights to deter Herman and then brutally kills him. The murder eliminates the external threat to their secret life. Afterward, they go out for dinner, continuing to bicker over cuisine while reaffirming their shared hatred of grapes.
