With a title like that I was expecting spooks on the high seas but this is about ghosts spreading their malign influence over the airwaves. It doesn’t quite make the grade as horror and ultimately feels like another average low-budget digitally shot film meant to cash in on the Ringu phenomena where ghosts use technology to get us.
At a TV network board meeting, Hiroshi Usui (Toshihiro Wada) is asked to boost ratings for his show ‘Akie Doma’s Exorcism’. The show draws people who love the supernatural as well as the mentally disturbed. It also draws the ire of a psychiatrist named Kawamura (Meikyo Yamada) who accuses Usui of exploiting the mentally unbalanced. Usui visits the house of an overzealous fan named Tsuyoshi Nagao (Masaki Miura) who lives with his sister Runa (Shihori Kanjiya) who he believes is possessed. Despite Runa’s protestations that the ghosts will be angry with an exorcism, Tsuyoshi and Usui make a deal allowing the filming of Runa’s exorcism. Akie Doma (Asuka Kurosawa) performs the exorcism. Strangely it is Tsuyoshi who has a violent physical reaction whilst Runa’s gaze is locked on something invisible that she apologises to. Later Usui is approached by Kawamura who reveals the phenomena of “Dead Waves”, radio waves that harbour vengeful spirits who use TV broadcasts to draw people into the world of death. Despite scepticism, Hiroshi is uneasy because he discovers disturbing information surrounding the Nagao’s and a revelation about his ex-girlfriend. The show with the Nagao’s is due to broadcast soon, could Dead Waves exist? Are the Nagao’s cursed by ghosts or is there something more mundane but just as deadly.
