A group of college students staying in a hostel close to a beach, practice their dance routine in a training camp for an upcoming dance competition.

Almost all of the dialogue and narration is extracted from the original story, and there are no particular deviations from the original storyline, but the images tend to be devoid of reality. For example, the scene in the ruins of the mansion where Saeki and Kindaichi talk to each other is somewhat fantastical, and Kindaichi's appearance is also unrealistic. In addition, Saeki and Yumi's sex life is represented by the 'dancing futon'. The behaviour of those attending the first anniversary of the death of Saeki and Yumi is unnaturally exaggerated.
