Mysterieuze wezens terroriseren een eiland en dwingen de lokale bevolking hun eens zo bloeiende huis te ontvluchten. Omdat er geen overheidsgeld is voor het uitroeien van monsters, koopt Tajima het enige overgebleven bouwbedrijf en transformeert het voor deze taak. Gelukkig komen de briljante Testuro Okino en zijn nieuwe robot, Bullbuster, hen te hulp. Maar het team heeft een krap budget. Kunnen zij het eiland redden?
