A prominent Japanese wrestler proposes an innovate solution to resolving a bitter rivalry after his new palatial palace is destroyed and his wife is transformed into a zombie mermaid. Zero is the biggest pro-wrestling organization in Japan, and Shishio (Shinya Hashimoto) is the proud leader of the prominant federation. In celebration of his sprawling new home, Shishio decides to throw a lavish party for all of his closest friends. But Shishio has his share of enemies, too, and when his chief rival Ichijoh (Nicolas Pettas) crashes the party and strong-arms a junior member of Zero into a fight, the deeply offended host really loses his cool. Before long, a battle royal has erupted on the palace and the house is in shambles. Somehow, Shishio's wife Asami is injured in the fray and seeks emergency medical treatment that turns the once-beautiful woman into a hideous zombie mermaid. Now, in order to rebuild his house and save his wife, Shishio stages a televised, multi-stage battle to the death in which he will fight zombies, monsters, and any wrestler foolish enough to challenge him. It's bound to get the biggest ratings ever, and with a little luck Shishio and his wife will be back on top of the world and living the good life.
