In her brother's apartment where he died, Yuki finds a vacuum cleaner with its cord still hooked up to the outlet. She discovers that the circumstances surrounding her brother's supposed suicide are sketchy at best, yet no one has any answers. When she starts having hallucinations involving his ghost, however, she seeks some psychological help, eventually uncovering some things that she may have wished she'd left covered.
Though lacking in production quality and some dubious choices in directional efforts in this obviously limited TV-production, once accepting the format and its premises it opens up into a quite compelling little narrative that grows well along the movie. The characters are interesting and have the feel of a genuine personality to them. It is in no way a masterpiece or cult material, but I find it worth a watch and maybe even a re-watch eventually.
