The popular classic returns, showcasing the gradual wetting of skirts as women lose control of their bladders. True to its title, this film focuses on the slow spread and darkening of urine stains across skirts. Using the familiar multi-screen format, it meticulously captures the moments of desperation, the act of involuntary urination, and the aftermath. Featured prominently is the highly sought-after transparent chair, adding intense visual impact. Four women struggle to hold their urine while riding a train, pressing their heels between their legs to stave off the urge until they finally give in, releasing a flood that soaks their skirts completely. Another scene shows a woman enduring a long job interview, unable to finish, until her skirt becomes drenched and urine pools on the chair beneath her, exposing her accident. A kind-hearted girl answers survey questions while desperately needing the toilet, but is denied access, resulting in a clearly visible stain spreading across her buttocks. A beautiful office worker tries to excuse herself during a meeting, but her boss stops her—unable to endure any longer, she stares upward helplessly as she suffers a massive incontinence episode. A release from Excretion House, with full facial exposure throughout the main feature.
