The elevator suddenly stops, trapping inside women who are struggling to hold their urine—this improbable scenario sets the stage for the film. A unique locked-room story centered around the theme of "what if" regarding excretion. Women become trapped in the elevator, forced to endure overwhelming urges to pee. How do they cope when others are present? Attempting to avoid accidents, they use containers and plastic bags, but it proves surprisingly difficult. The film depicts their desperate efforts with plastic bottles and bags. One woman, reaching her limit, borrows a plastic bag only for it to tear, soaking the floor completely. A petite, animal-like gyaru girl squirms and presses her crotch without caring about onlookers. With help from others, she successfully releases into a vacuum pack. A uniformed schoolgirl narrowly avoids disaster by using a gum bottle, shielding her groin with her bag while clenching tightly. Alternating between two bottles to prevent leakage, she eventually shifts to a plastic cup as her urine volume increases. A voluptuous woman grows restless at one point, skillfully filling two cups in succession. Another, a half-Japanese beauty, makes an emergency switch to a PET bottle, calmly enduring despite her painfully full bladder. When she finally reaches her limit, she gasps for breath while unleashing nearly one liter into the bottle. A distinctive excretion narrative unfolds, featuring full-face appearances and an intense collection of confined pissing scenes.
