Groper Train: Groping the Secret Core

The story follows Shinji, who finds himself on a train after his Caravan is in for repairs. During his journey, he witnesses a woman named Nana being groped, and their ensuing relationship leads to an unexpected partnership in a black-and-white show. This performance space showcases Nana's amateur talents, which quickly become a hit with audiences, resulting in sold-out shows.

As the narrative unfolds, the dynamics between Shinji, Nana, and other characters deepen, particularly when Nana receives an ocarina from a middle-aged customer, leading to her sudden disappearance. The film's exploration of complex interactions and the grittiness of its pink film genre contribute to its distinct appeal.
