What Is Under the Yum-Yum Tree About?
The premise of Under the Yum-Yum Tree in 300 words, with nothing given away. The full story follows below.
In a California apartment block that doubles as a self-styled temple of temptation, Hogan reigns supreme as a landlord with a singular vision. A swinging bachelor of independent wealth, he has curated his building with blood-red walls, African sculptures, and a switch-operated fireplace, transforming it into a stage for seduction. He rents rooms exclusively to gorgeous single women at a modest rate, presenting himself as a charming host of hedonistic pleasures. Clad in a scarlet cardigan with a devilish smirk, Hogan operates with a confidence that borders on self-delusion, treating his residence as a private kingdom where he dictates the rules of romance.
The arrival of Robin Austin, a bright and capable new tenant, seems to offer Hogan another opportunity for conquest, yet her residency brings unexpected complications. She is accompanied by her frustrated boyfriend, David Manning, who moves in under the guise of a platonic arrangement intended to test the couple’s compatibility. Hogan, ever the schemer, views David not as a true rival but as an obstacle to be outmaneuvered. As the landlord deploys his considerable charm and theatrical tricks to undermine the couple’s bond, the apartment becomes a pressure cooker of jealousy and wit, with Hogan striving to blur the lines between social rapport and romantic pursuit.
Watching from the sidelines is Irene, Robin’s aunt and a former tenant who is all too familiar with Hogan’s manipulative patterns. Having recently extricated herself from his orbit, she serves as a wary guardian determined to protect her niece from the landlord’s lecherous intentions. As the characters navigate the thin walls and thinner excuses within the building, the atmosphere thickens with comedic tension. The film captures the absurdity of Hogan’s relentless pursuit, blending humor with a sharp observation of how boundaries are tested when desire and self-deception collide under one roof.

Spoilers ahead
Hogan [Jack Lemmon] is a lecherous landlord and a swinging bachelor who treats his California apartment block as a private stage for seduction. He ogles and tries to charm his female tenants, turning the building into a bold, self-contained temple of temptation: blood-red walls, African sculptures, a well-stocked cocktail bar, a switch-operated fireplace, and mechanized violins that glide into music at the touch of a button. He moves through the space in a scarlet cardigan with matching socks and a devilish smirk, presenting himself as a confident, often self-deluded host of hedonistic pleasures. As the independently wealthy owner, he rents rooms only to gorgeous single women for a modest $75 a month, while an older married couple—handyman Murphy [Paul Lynde] and his maid Dorcas—keep Hogan’s operation running with a practiced, theatrical efficiency.
Irene, a recently divorced tenant, has just ended a relationship with Hogan and is moving out with the help of a friend Charles. The vacancy is quickly filled by her niece Robin [Carol Lynley] Austin, a bright, capable young woman who brings new energy to the building. Robin’s presence is soon complicated by a short-tempered, frustrated, bumbling boyfriend, David Manning [Dean Jones], who moves in with her under the guise of a platonically arranged test of compatibility.
Hogan, ever eager for another beautiful tenant to charm, is initially delighted by Robin’s arrival, even as he remains oblivious to the fact that David will be sharing the space. He uses every trick in his playbook to keep the line between romance and trespass blurred, trying to prevent David and Robin from moving toward anything more than a social rapport. The tension thickens as Irene, having grown wary of Hogan’s rampant promiscuity, resolves to shield her niece from being pulled into Hogan’s orbit.
The confrontation escalates when Irene confronts Hogan at his barber, exposing the far more naked truth behind his charm: a pattern of manipulation and scheming that few of his tenants truly escape. Hogan responds with a blend of defensiveness and comic self-delusion, insisting on his own cleverness even as the situation spirals toward an inevitable reckoning. In this delicate balancing act of desire, control, and consequence, the film threads humor with a wary, observational tone, keeping the focus on how each character navigates loyalty, temptation, and personal boundaries within a single, carefully curated California residence.
